In portions
of this annual report, we have translated New Taiwan dollar amounts into U.S. dollars for the convenience of readers. The rate we used for the translations was NT$32.59 = US$1.00, which was the noon buying rate in the City of New York for cable
transfers of New Taiwan dollars as certified for customs purposes by the Federal Reserve Bank of New York on December 29, 2006. This translation does not mean that New

Taiwan dollars could actually be converted into U.S. dollars at that or any other rate or at all. The following table shows the noon buying rates for New
Taiwan dollars expressed in New Taiwan dollar per US$1.00.

Annual averages are calculated using the average of the exchange rates on the last day of each month during the period. Monthly averages are calculated using the average of the
daily rates during the relevant period.

Our business and operations are subject to various risks, many of which are beyond our control. If any of the risks described
below actually occurs, our business, financial condition or results of operations could be seriously harmed.

Risks Relating to Our Company and the
Taiwan Telecommunications Industry

Before we were
privatized in August 2005, our business and operations were subject to extensive regulation under Republic of China laws, rules and regulations applicable to state-owned enterprises. As a result, we only have a very limited history of operations as
a non-state-owned enterprise. We cannot assure you that we will be successful in achieving the benefits we expect from our privatization, such as increased management flexibility in implementing measures to improve our cost structure, efficient
operations of our business and expansion into new businesses in a timely manner or at all. Factors that may cause the actual benefits we may enjoy from privatization to deviate from our expectations include:



adverse developments in our relations with our labor union that affect our costs, including with respect to compensation and other benefits, and efficient
management of our workforce;



increased costs with respect to our plans to incentivize employees through contributions to employee child education funds, performance-based cash bonuses and
company subsidized purchases by employees of our common shares;

As a telecommunications service provider in Taiwan, we are subject to extensive regulation. Any changes in the
regulatory environment applicable to us may adversely affect our business, financial condition and results of operations.

Prior to
March 1, 2006, we were under the supervision of the Ministry of Transportation and Communications and the Directorate General of Telecommunications. On March 1, 2006, the National Communications Commission was formed in accordance with the
National Communications Commission Organization Law, or Organization Law, which was intended to transfer regulatory authority over the Taiwan telecommunications industry from the Ministry of Transportation and Communications and the Directorate
General of Telecommunications to the National Communications Commission.

The National Communications Commission is currently comprised of
nine commissioners who have been recommended by the government and opposition political parties in the Legislative Yuan, as well as recommended by the Executive Yuan and approved by the Legislative Yuan. However, the Executive Yuan considered the
composition of the National Communications Commission unconstitutional and petitioned the Grand Justices of the Republic of China, or the Grand Justices, to interpret the constitutionality of the formation of the National Communications Commission
and the procedure for nominating commissioners to serve on the National Communications Commission. On July 21, 2006, the Grand Justices rendered an interpretation and held that the relevant provisions under the Organization Law as to the
nomination procedures for the commissioners of the National Communications Commission were unconstitutional. However, the Grand Justices granted a grace period allowing such provisions of the Organization Law to remain in effect until
December 31, 2008. Consequently, the National Communications Commission will have the authority at least until the end of 2008. As of the date of this annual report, the Ministry of Transportation and Communications is responsible for
determining the policies for the telecommunications industry while the National Communications Commission is responsible for supervising the telecommunications industry and maintaining fair competition. Any changes in the regulatory environment
applicable to us may adversely affect our business, financial condition and results of operations.

We have been designated by the
government as a dominant provider of fixed line and cellular services within the meaning of applicable telecommunications regulations, and as a result, we are subject to special additional requirements imposed by the National Communications
Commission. For example, the regulation governing setting and changing of tariffs allows non-dominant telecommunications service providers greater freedom to set and change tariffs within the range set by the government. If we are unable to respond
effectively to tariff changes by our competitors, then our competitiveness, market position and profitability will be materially and adversely affected. We were subject to the Statute of Chunghwa Telecom Co., Ltd. prior to our privatization.
Although we have been privatized, the Legislative Yuan has not yet abolished the Statute of Chunghwa Telecom Co., Ltd., and at this time, the Statute of Chunghwa Telecom Co., Ltd. is still applicable to us. Under the Statute of Chunghwa Telecom Co.,
Ltd., the Ministry of Transportation and Communications has the authority to regulate aspects of our business. Any such regulation could be burdensome or conflict with regulations of the National Communications Commission or may otherwise adversely
affect our business, financial condition and results of operations.

The regulatory framework within which we operate may limit our
flexibility to respond to market conditions, competition or changes in our cost structure. In particular, future decreases in tariff policies and rates could immediately and substantially decrease our revenues. In particular, as a Type I service
provider under the

Telecommunications Act, we are constrained in our ability to raise tariffs. Furthermore, the National Communications Commission adopted a price reduction
plan on December 12, 2006 and is considering a number of changes to the tariff structures relating to our local telephone, cellular and leased line services. See Item 5 Operating and Financial Review and
ProspectsOverviewTariff Adjustments.

In addition, we operate our businesses with approvals and licenses granted by the
government. If these approvals or licenses are revoked or suspended or are not renewed, or if we are unable to obtain any additional licenses that we may need to operate or expand our business in the manner we desire, then our financial condition
and results of operations, as well as our prospects, will suffer. For example, in April 2007, the National Communications Commission began to accept license applications according to the Regulation Governing the Worldwide Interoperability for
Microwave Access, or WiMAX, and announced that it planned to issue six WiMAX licenses. WiMAX is a standards-based technology providing high-speed mobile data and telecommunications services and enabling wireless delivery of last mile broadband
access as an alternative to cable and digital subscriber line. We may be unable to obtain a WiMAX license that we may need to provide the next generation telecommunication services.

We have faced increasing
competition from new entrants in the Taiwan telecommunications market in recent years. In particular, multiple licenses to operate fixed line, cellular, paging and other services have been issued by the Republic of China government since 1996.
Furthermore, three additional operators began providing fixed line services in June 2001, and licenses were granted to four undersea cable operators to engage in the undersea cable leased-circuit business in August 2001. In addition, the government
awarded third generation, or 3G, cellular services concessions to five companies in February 2002, including two new cellular operators. Since early 2004, the government has also issued four mobile virtual network operator licenses that allow
operators without a spectrum allocation to provide cellular services by leasing the network capacity and facilities from a licensed cellular service provider.

We also face increased competition from local loop unbundling. We first entered into agreements regarding local loop unbundling of voice with New Century InfoComm Tech. Co., Ltd., or Sparq, in March 2004, and with
Taiwan Fixed Network and Asia Pacific Broadband Telecom in May 2004. We subsequently entered into an agreement for full local loop unbundling of both voice and data with Sparq in July 2005. In January 2007, the National Communications Commission
requested each dominant integrated services operator, including us, to reserve fifteen percent of its local loop for leasing to other service operators unless the then remaining available local loop of the operator not leased out is less than
fifteen percent, in which case the operator should reserve such remaining loop. In addition, the National Communications Commission had defined the local loop as facilities at the bottleneck of telecommunications networks in accordance
with the Regulations Governing Fixed Network Telecommunications Businesses The National Communications Commission further amended the Administrative Rules for Network Interconnection Between Telecommunication Service Providers in April 2007 which
provides that we can only charge other local telephone service providers at cost for local loop services instead of on the basis of commercial negotiations.

Many of our competitors are in alliances with leading international telecommunications service providers and have access to financial and other resources or technologies that may not be available to us. Moreover, as
the government continues to liberalize the telecommunications market, such as through the issuance of new licenses or establishment of additional networks, our market position and competitiveness could be materially and adversely affected.

In addition, the focus of competition among cellular service providers in Taiwan has been shifting, as companies that traditionally
offered second generation services, such as us, began offering 3G services, and as new 3G service providers started to enter the market. As a result, we expect competition in 3G services to continue to intensify. We may also be subject to
competition from providers of new telecommunications services

as a result of technological development and the convergence of various telecommunications services. In particular, as a result of technological innovations
and other factors, we have been facing competition from alternative means of communication, including voice over internet protocol, or VoIP, high-speed cable internet service, cable telephony, e-mail and wireless services. Providers of these
products and services include cable television companies, direct broadcast satellite companies and digital subscriber line, or DSL, resellers.

Increasing competition may also cause the rate of our customer growth to reverse or decline, bring about further decreases in tariff rates and necessitate increases in our selling and promotional expenses. Any of these developments could
materially and adversely affect our business growth and profitability, as well as our financial condition and results of operations.

As of the date of this annual report, almost all of our employees were members of our principal labor union. Since our incorporation in 1996, we have
experienced disputes with our labor union on such issues as employee benefits and retirement benefits in connection with our privatization as well as the right to protest. In particular, our labor union initiated a demonstration in August 2000 to
express concerns over job security after our privatization. Furthermore, following our failure to sign the collective agreement proposed by the labor union, the union resolved on December 5, 2004 to hold strikes anytime before our
privatization. In response to our proposed privatization, the labor union held a strike on May 17, 2005. The labor union also strongly opposed our privatization and has threatened to launch a nationwide strike or take other forms of action to
hinder our privatization. In addition, one of our directors has been designated by the Republic of China government as a labor union representative on our board. Any deterioration of our relationship with our labor union could result in work
stoppages, strikes or threats to take such an action, which could disrupt our business and operations, and materially and adversely affect the quality of our services and harm our reputation. The latest collective bargaining agreement, which was
entered into between us and our labor union on January 6, 2006 and commenced in effect from March 3, 2006, will result in us having to incur higher costs in connection with the implementation of certain incentive programs, including
employee skill development programs, as well as employee child education funds, company subsidized share purchases by employees, and discretionary, performance-based cash bonuses. We cannot accurately quantify the increase in costs at this time, but
we expect that it may be material.

The Taiwan telecommunications industry has been characterized by rapid increases in the diversity and sophistication of the technologies and services offered. As a result, we expect that we will need to constantly
upgrade our telecommunications technologies and services in order to respond to competitive industry conditions and customer requirements. Developments of new technologies have rendered some less advanced technologies unpopular or obsolete. For
example, demand for our paging services has declined significantly since the introduction of GSM services, improvements in other technologies and changes in the market. As a result, we recognized an impairment charge of NT$343 million (US$10.5
million) relating to our paging business in 2005. If we fail to develop, or to obtain timely access to, new technologies and equipment, or if we fail to obtain the necessary licenses to provide services using these new technologies, we may lose our
customers and market share and become less profitable. For example, we began offering multimedia on demand, or MOD, services in March 2004. Although we were not, and are not, in compliance with some applicable ownership restrictions under the Cable
Radio and Television Law of the Republic of China, or the Cable Radio and Television Law, we were nevertheless granted a permit as a fixed line operator to offer cable television services by the Government Information Office, the regulatory
authority previously governing the cable television industry. In January 2007, the National Communications Commission, after reviewing our improvement in opening of platform of the MOD

service, held that we had complied with the request in its order and therefore we would not be considered a cable, radio or television system operator under
the Cable Radio and Television Law with respect to this business. Consequently, we are not currently subject to such ownership restrictions. However, the National Communications Commission did announce that it would further amend the Regulation
Governing Fixed Line Services in order to regulate the MOD service provided by fixed line operators and would then ask us to submit our operation rules, tariff and service agreement for MOD services for its review. We cannot predict the outcome of
this review and cannot assure you that further amendments would not subject us to ownership restrictions or other limitations on our MOD business. Moreover, our plans to introduce VoIP telephone services have also been delayed because we have not
received requisite approvals from the applicable regulatory authority.

In addition, the cost of implementing new technologies, upgrading
our networks or expanding capacity could be significant. In particular, we have made and will continue to make substantial capital expenditures in the near future in order for us to effectively respond to technological changes, such as the continued
expansion of our 3G cellular mobile network. We will also need to make additional capital expenditures relating to the launch of new businesses, including MOD, ADSL services, fiber-to-the-building services WiMAX and VoIP services, and the
implementation of a network modernization program, including the planned migration of our fixed line networks to internet protocol next generation networks. To the extent these expenditures exceed our cash resources, we will be required to seek
additional debt or equity financing. Our ability to obtain additional financing on favorable commercial terms will depend on a number of factors. These factors include our financial condition, results of operations, cash flows and the prevailing
market conditions in the Taiwan and international telecommunications industry, the cost of financing and conditions in the financial markets, and the issuance of relevant government and other regulatory approvals. The failure to obtain funding for
our capital expenditures on commercially acceptable terms and on a timely basis, or at all, could jeopardize our expansion plans and materially and adversely affect our business, financial condition, results of operations and prospects.

We have made significant capital investments in our network infrastructure and information technology
systems to provide the services we offer. In 2006, we had capital expenditures in relation to our network infrastructure and information technology systems of NT$27.7 billion. Of this amount, we had capital expenditures of NT$5.4 billion in our
fixed line services, NT$9.4 billion in our cellular services, NT$12.5 billion in our internet and data services and NT$0.4 billion in other areas. In order to continue to develop our business and offer new and more sophisticated services, we intend
to continue to invest in these areas as well as new technologies. The launch of new and commercially viable products and services is important to the success of our business. We expect to incur substantial capital expenditures to further develop our
range of services and products. Commercial acceptance by consumers of new and more sophisticated services we offer may not occur at the rate or level expected, and we may not be able to successfully adapt these services to effectively and
economically meet our customers demand, thus impairing our expected return from our investments.

We cannot assure you that services
enabled by new technologies we implement, such as 3G cellular technology, will be accepted by the public to the extent required to generate an acceptable rate of return. In addition, we face the risk of unforeseen complications in the deployment of
these new services and technologies, and we cannot assure you that our estimate of the necessary capital expenditure to offer such services will not be exceeded. New services and technologies may not be developed and/or deployed according to
expected schedules or may not achieve commercial acceptance or be cost effective. The failure of any of our services to achieve commercial acceptance could result in additional capital expenditures or a reduction in profitability to the extent that
we are required under the applicable accounting standards to recognize a charge for the impairment of assets. Any such charge could materially and adversely affect our financial condition and results of operations.

We may also from time to time make equity investments in companies, but we cannot assure you of their profitability. For example, Chunghwa Investment
Co., Ltd, a company in which we hold a 49% interest and which we account for using the equity method, suffered losses in 2004. As a result, the carrying value of

Chunghwa Investment in our consolidated financial statements was reduced from NT$987 million in 2003 to NT$930 million in 2004. These losses were partially
attributable to the write-off of certain short-term investments in the amount of NT$80 million that were not authorized by Chunghwa Investment, but were made by the then chairman of Chunghwa Investment, Mr. Jing-Biao Hu, who was removed from
office on December 31, 2004. In addition, another of our investments, the Taipei Financial Center Corporation, in which we hold a 12% interest and which we account for using the cost method, commenced commercial operations after completing
construction of Taipei 101, which it owns and which is the tallest building in Taiwan. In 2005, we recognized a loss of NT$740 million in relation to this investment due to lower than expected leasing rates for office and retail space in Taipei 101.
We cannot assure you that any unprofitable equity investments will not have a material adverse effect on our financial condition or results of operations.

Our services are currently carried through our fixed line and cellular telecommunications networks, as well as through our transmission networks comprised of optical fiber cable, microwave, submarine cable and
satellite transmission links. Our networks may be vulnerable to damage or interruptions in operations due to adverse weather conditions, earthquakes, fires, power loss, telecommunications failures, software flaws, transmission cable cuts or similar
events. For example, on December 26, 2006, a 6.9 magnitude earthquake in the southern seas of Taiwan caused significant damage to the undersea cable networks that connect Taiwan to the United States, Japan, Hong Kong, China and other countries
in South East Asia. The earthquake resulted in major outages in telephone and internet services throughout the region. It took one week to restore 90% of the capacity and repairs were not completed until February 2, 2007, when all four affected
undersea cables finally returned to normal operations. As a result of the December 2006 earthquake, we suffered repair costs of approximately NT$10 million. Taiwan is susceptible to earthquakes and typhoons, however, we do not carry any insurance to
cover damages caused by earthquakes, typhoons or other natural disasters, or to cover any resulting business interruption. Any failure of our networks, servers, or any link in the delivery chain that results in an interruption in our operations or
an interruption in the provision of any of our services, whether from operational disruption, natural disaster, military or terrorist activity, or otherwise, could damage our ability to attract and retain subscribers and materially and adversely
affect our business, financial condition, results of operations and prospects.

We are pursuing a number of new growth opportunities in the broader telecommunications industry, including wireless data services, MOD services and VoIP, WiMAX. These opportunities involve new services for which there
are no proven markets. Our ability to deploy and deliver these services will depend, in many instances, on new and unproven technologies. These new technologies, such as 3G cellular telecommunications technologies, may not perform as expected or
generate an acceptable rate of return. In addition, we may not be able to successfully develop new technologies to effectively and economically deliver these services, or be able to compete successfully in the delivery of telecommunications services
based on new technologies. Furthermore, the success of our wireless data services is substantially dependent on the availability of wireless data applications and devices that are being developed by third-party developers. These applications or
devices may not be sufficiently developed to support the deployment of our wireless data services. If we are unable to deliver commercially viable services based on the new technologies that we adopt, then our revenue growth and profitability, as
well as our financial condition and results of operations, will be materially and adversely affected.

We depend on the continued service of our executive officers and skilled technical and
other personnel. Our business could suffer if we lose the services of any of these personnel and cannot adequately replace them. In

particular, we are not insured against the loss of any of our personnel. Moreover, we may be required to increase substantially the number of these employees
in connection with any expansion, and there is intense competition for experienced personnel in the Taiwan telecommunications industry. We may not be able to either retain our present personnel or attract additional qualified personnel as and when
needed. In addition, we may need to increase employee compensation levels in order to attract and retain personnel. We cannot assure you that the loss of the services of any of these personnel would not disrupt our business and operations, and
materially and adversely affect the quality of our services and harm our reputation.

As of April 17, 2007, the Republic of China government, through the Ministry of
Transportation and Communications, owned approximately 35.41% of our outstanding common shares. Accordingly, the government, through its control over our board, may continue to have the ability to control our business, including matters relating to:



any sale of all or substantially all of our assets;



the approval of our annual operation and projects budget;



the composition of our senior management;



the timing and distribution of dividends;



the election of a majority of our directors and supervisors; and



our business activities and direction.

In addition, pursuant to the Republic of China Telecommunications Act, or the Telecommunications Act, and our articles of incorporation, our board of directors approved the issuance of two preferred shares on March 28, 2006 to the
Ministry of Transportation and Communications. As the holder of these preferred shares, the Ministry & Transportation and Communications has the right to veto any change in our name or our business and any transfer of the whole or the main
part of our business or property and to act as a director and supervisor on the basis of its preferred shareholding. Under our articles of incorporation, these preferred shares are non-transferable and will be redeemed by us three years after the
record date of their issuance at their par value.

The government may continue to sell our common shares. Sales of
substantial amounts of ADSs or common shares by the government or any other shareholder in the public market, or the perception that future sales may occur, could depress the prevailing market price of our ADSs and common shares.

The laws of the Republic of China limit foreign ownership of our common shares. Prior to
March 1, 2006, the Ministry of Transportation and Communications, as the competent authority under the Telecommunications Act, had the power to prescribe the limits on foreign ownership of our common shares. After the formation of the National
Communications Commission, on March 1, 2006, the National Communications Commission replaced the Ministry of Transportation and Communications as the competent authority under the Telecommunications Act pursuant to the Organization Law.
However, it is unclear whether the National Communications Commission (instead of the Ministry of Transportation and Communications) has the authority to prescribe the limits of foreign ownership of our common shares. On July 19, 2006, the
Ministry of Transportation and Communications increased our foreign ownership limitation from 40% to 49% pursuant to the Telecommunications Act. Since our foreign ownership is now above 40%, we could be deemed in violation of the foreign ownership
limitations if it is determined that the Ministry of Transportation and Communications did not have authority to increase our foreign ownership limit to 49% as it purported to do on July 19, 2006. If we fail to comply with the applicable
foreign ownership limitations, our licenses to operate some of our businesses could be revoked. Moreover, we

cannot predict the manner in which the National Communications Commission will exercise its authority over us, and the National Communications Commission
could decline to raise, or determine to reduce, this foreign ownership limitation.

In addition, the Cable Radio and Television Law, under
which we operate our MOD business, provides that direct foreign ownership in a cable operator may not exceed 20%, and that the combined direct and indirect foreign ownership in a cable operator may not exceed 60%. We were granted a license under
this law, even though we were not, and are not, in compliance with this and other ownership restrictions. However, the National Communications Commission, which has been responsible for administering regulations in this area since March 1,
2006, issued an order on August 23, 2006 requesting us to open our MOD services platform to non-Chunghwa Telecom HiNet subscribers and other service operators and content providers by December 31, 2006. In January 2007, the National
Communications Commission, after reviewing the opening in our platform for MOD service, held that we had complied with the request in its order and therefore we would not be considered a cable, radio or television system operator under the Cable
Radio and Television Law with respect to this business. Consequently, we are not subject to such ownership restrictions. However, the National Communications Commission did announce that it would further amend the Regulation Governing Fixed Line
Services in order to regulate the MOD service provided by fixed line operators and would then ask us to submit our operation rules, tariff and service agreement for MOD services for its review. We cannot predict the outcome of such review and we
cannot assure you that further amendment would not subject us to ownership restrictions or other limitations on our MOD business.

Since it
is unclear whether the National Communications Commission or the Ministry of Transportation and Communications has the authority to exercise power with respect to raising our foreign ownership limitations, we cannot assure you that we are not in
violation of the limits on our foreign ownership under the Telecommunications Act. If we are deemed to be in violation of our foreign ownership limitations, any consequences arising from such violation may materially and adversely affect us.
Moreover, since we are unable to control ownership of our common shares or ADSs representing our common shares, and because we have no ability to stop transfers among shareholders, or force particular shareholders to sell their shares, we may be
subject to monetary fine or lose our licenses through no fault of our own. In that event, our business could be disrupted, our reputation could be damaged and the market price of our ADSs and common shares could decline. These limitations may also
materially and adversely affect our ability to obtain adequate financing to fund our future capital requirements or to obtain strategic partners, and alternate forms of financing may not be available on terms favorable to us or at all.

According to some published reports, the electromagnetic signals from
cellular handsets and cellular base stations may pose health risks or interfere with the operation of electronic equipment. Although the findings of those reports are disputed, actual or perceived risks of using cellular telecommunications devices
or of base stations could have a material adverse effect on cellular service providers, including us. For example, our customer base could be reduced, our customers may reduce their usage of our cellular services, we could encounter difficulties in
obtaining sites for additional cellular base stations required to expand our network coverage or we may be requested to reduce the number of existing cellular base stations. As a result, our cellular business may generate less revenue and our
financial condition and results of operations may be materially and adversely affected. In addition, we could be exposed to potential liability for any health problems caused by cellular handsets and base stations.

Our ongoing financial reporting with the SEC is currently under
US GAAP. Beginning in 2008, we plan to prepare our financial reporting with the SEC under generally accepted accounting principles in the Republic of

China, or ROC GAAP, with reconciliation to US GAAP in accordance with the requirements of the SEC. Our reported financial condition and results of
operations under US GAAP may differ significantly from ROC GAAP. The price of our common shares trading on the Taiwan Stock Exchange may be based on, among other things, our consolidated financial statements prepared for ongoing reporting
purposes in the Republic of China, and this in turn may affect the market price of our ADSs.

We are from time to time involved in litigation, arbitration or administrative proceedings in the ordinary
course of our business. See Item 4. Information on the CompanyB. Business OverviewLegal Proceedings. We cannot predict the outcome of these proceedings, and we cannot assure you that if a judgment is rendered against us in
any or all of these proceedings, our financial condition and results of operations would not be materially and adversely affected.

We are subject to the reporting requirements of the SEC. The SEC, as directed by Section 404 of the U.S. Sarbanes-Oxley Act of 2002, adopted rules
requiring U.S. public companies to include a report of management on our internal control over financial reporting in their annual reports that contain an assessment by management of the effectiveness of the companys internal control over
financial reporting. In addition, each companys independent registered public accountants must attest to and report on the design and operating effectiveness of and managements assessment of the effectiveness of the companys
internal control over financial reporting. These requirements first applied to us in connection with our annual report on Form 20-F for the fiscal year ending on December 31, 2006.

While the management report included in this annual report concluded that our internal control over financial reporting was effective, we cannot assure
you that our management will be able to conclude that our internal control over financial reporting is effective in future years. Moreover, even if our management concludes that our internal control over financial reporting is effective, our
independent registered public accounting firm may still conclude that our internal control is not effective due to any inability to fully remedy the material weaknesses already reported to our audit committee by our independent registered public
accounting firm or additional material weaknesses that may be identified during the Section 404 audit process or other reasons. If in future years we fail to achieve and maintain effective internal control over financial reporting in accordance
with the Sarbanes-Oxley Act, we could suffer a loss of investor confidence in the reliability of our consolidated financial statements, which in turn could negatively impact the trading price of our ADSs, result in lawsuits being filed against us by
our shareholders or otherwise harm our reputation. Furthermore, we have incurred and anticipate that we will continue to incur considerable costs and use significant management time and other resources in our efforts to comply with Section 404
and other requirements of the Sarbanes-Oxley Act.

We have recently begun investing in real estate revitalization projects as part of our
efforts to make more productive use of certain undeveloped or underdeveloped properties that we own. Our revitalization projects include the development of high-tech residences, commercial offices and resorts. As of the date of this annual report,
we have six such projects underway relating to properties in and around Taipei and other parts of Taiwan. We have no prior experience operating real estate development projects and cannot assure you that our investments will achieve their expected
results. Operating or investing in real estate projects involves numerous risks for which we may not be adequately protected. Many of these risks are also beyond our control. For example, our projects may be delayed or never completed due to the
failure of other parties with which we have contracted to fulfill their contractual obligations or because of unexpected problems that arise during the planning or construction phases of the projects. Any significant delay or any failure to complete
our projects

might result in our projects not achieving their expected return and could subject us to a loss on our investment. In addition, changes in the regulatory or
economic environment relating to real estate, such as changes in interest rates affecting the financing of our projects, increases in the applicable property tax rates relating to our properties and decreases in demand for residential, commercial or
resort properties, could adversely affect the value of our properties and/or reduce or eliminate the profitability of our projects. If our revitalization projects do not achieve their expected results or subject us to a significant financial loss,
this could have a adverse effect on our financial condition and results of operations.

We conduct
most of our operations and generate most of our revenues in Taiwan. As a result, any decline in the Taiwan economy or a decline in the growth of the population in Taiwan may materially and adversely affect our financial condition, results of
operations and prospects. In recent years, the banking and financial sectors in Taiwan have been seriously harmed by the general economic downturn in Taiwan and the rest of Asia, which has resulted in a depressed property market and an increase in
the number of companies filing for corporate reorganization and bankruptcy protection. Although economic conditions in Taiwan improved since 2003, the global slowdown in technology expenditures has also from time to time adversely affected the
Taiwan economy, which is highly dependent on the technology industry. We cannot assure you that economic conditions in Taiwan will continue to improve in the future or that our business and operations will not be materially and adversely affected by
a deterioration in the Taiwan economy.

Our principal executive offices and substantially all of our assets are located in Taiwan, and substantially all of our revenues are derived from our
operations in Taiwan. Accordingly, our business, financial condition and results of operations and the market price of our common shares and the ADSs may be affected by changes in Republic of China governmental policies, taxation, inflation or
interest rates and by social instability and diplomatic and social developments in or affecting Taiwan which are outside of our control. For example, in 2006 a mass movement formed calling for the resignation of the president of Taiwan over a series
of alleged corruption scandals and staged dramatic protests. In addition, Taiwan has a unique international political status. Since 1949, Taiwan and the Chinese mainland have been separately governed. The Peoples Republic of China, or PRC,
claims that it is the sole government in China and that Taiwan is part of China. Although significant economic and cultural relations have been established during recent years between the Republic of China and the PRC, relations have often been
strained. The PRC government has refused to renounce the use of military force to gain control over Taiwan. Furthermore, the PRC government passed an Anti-Secession Law in March 2005, which authorizes non-peaceful means and other necessary measures
should Taiwan move to gain independence from the PRC. In February 2006, the president of Taiwan ceased activities of the countrys National Unification Council, a committee established to assist Taiwan in its efforts to reunite with the PRC.
Such cessation is commonly viewed as having a detrimental effect on relations between the two countries. Past developments in relations between the Republic of China and the PRC have on occasion depressed the market prices of the securities of
companies in the Republic of China. Relations between the Republic of China and the PRC and other factors affecting military, political or economic conditions in Taiwan could materially and adversely affect our financial condition and results of
operations, as well as the market price and the liquidity of our securities.

Any future outbreak of contagious
diseases, such as severe acute respiratory syndrome or avian influenza, may disrupt our ability to adequately staff our business and may generally disrupt our operations. If any of our employees is suspected of having contracted any contagious
disease, we may under certain circumstances be

required to quarantine such employees and the affected areas of our premises. As a result, we may have to temporarily suspend part or all of our operations.
Furthermore, any future outbreak may restrict the level of economic activity in affected regions, including Taiwan, which may adversely affect our business and prospects. As a result, we cannot assure you that any future outbreak of contagious
diseases would not have a material adverse effect on our financial condition and results of operations.

Our
corporate affairs are governed by our articles of incorporation, the Telecommunications Act, and by the laws governing corporations incorporated in the Republic of China. In addition, our corporate affairs may remain governed by the Statute of
Chunghwa Telecom Co., Ltd. See Extensive regulation of our industry may limit our flexibility to respond to market conditions and competition, and our business may suffer. The rights of shareholders and the responsibilities of
management and the members of the board of directors of Taiwan companies are different from those applicable to a corporation incorporated in the United States. For example, controlling or major shareholders of Taiwan companies do not owe fiduciary
duties to minority shareholders. As a result, holders of our common shares and ADSs may have more difficulty in protecting their interests in connection with actions taken by our management or members of our board of directors than they would as
public shareholders of a United States corporation.

Our common shares are traded on the Taiwan Stock Exchange, which has a smaller
market capitalization and is more volatile than the securities markets in the United States and many European countries. The market value of our ADSs may fluctuate in response to the fluctuation of the trading price of our common shares on the
Taiwan Stock Exchange. The Taiwan Stock Exchange has experienced substantial fluctuations in the prices and trading volumes of listed securities and there are currently limits on the range of daily price movements. In recent years, the Taiwan Stock
Exchange Index reached a peak of 10,202.20 in February 2000 and subsequently fell to a low of 3,446.26 in October 2001. During 2006, the Taiwan Stock Exchange Index peaked at 7,823.72 on December 29, 2006, and reached a low of 6,257.80 on
July 17, 2006. On April 20, 2007, the Taiwan Stock Exchange Index closed at 7,942.67. The Taiwan Stock Exchange has experienced certain problems, including market manipulation, insider trading and payment defaults. The recurrence of these or
similar problems could have a material adverse effect on the market price and liquidity of the securities of Taiwan companies, including our ADSs and common shares, in both the domestic and the international markets.

In response to declines and volatility in the securities markets in Taiwan, the Republic of China government formed the National Financial Stabilization
Fund to support these markets through open market purchases of shares in Taiwan companies from time to time. The details of the transactions of the National Financial Stabilization Fund have not been made public. In addition, the governments
Labor Insurance Fund and other funds associated with the government have in the past purchased, and may from time to time purchase, shares of Taiwan companies listed on the Taiwan Stock Exchange or other markets. As a result of these activities, the
market price of common shares of Taiwan companies may have been and may currently be higher than the prices that would otherwise prevail in the open market. Market intervention by government entities, or the perception that such activity is taking
place, may take place or has ceased, may cause sudden movements in the market prices of the securities of Taiwan companies, which may affect the market price and liquidity of our common shares and ADSs.

The ability to
deposit shares into our ADS program is restricted by Republic of China law, under which no person or entity, including you and us, may deposit our common shares into our ADS program unless the

Securities and Futures Bureau has not objected within a prescribed period following the filing with it of an application to do so, except for the deposit of
the common shares into our ADS program and for the issuance of additional ADSs in connection with:



distribution of share dividends or free distribution of our common shares;



exercise of preemptive rights of ADS holders applicable to the common shares evidenced by our ADSs in the event of capital increases for cash; or



purchases of our common shares in the domestic market in Taiwan by the investor directly or through the depositary and delivery of such shares or delivery of our
common shares held by such investors to the custodian for deposit into our ADS program, subject to the following conditions: (a) the depositary may accept deposit of those shares and issue the corresponding number of ADSs with regard to such
deposits only if the total number of ADSs outstanding after the deposit does not exceed the number of ADSs previously approved by the Securities and Futures Bureau, plus any ADSs issued pursuant to the events described above; and (b) this
deposit may only be made to the extent previously issued ADSs have been cancelled.

As a result of the limited ability to
deposit common shares into our ADS program, the prevailing market price of our ADSs on the New York Stock Exchange may differ from the prevailing market price of the equivalent number of our common shares on the Taiwan Stock Exchange.

Holders of American depositary receipts evidencing our ADSs may exercise voting
rights with respect to the common shares represented by these ADSs only in accordance with the provisions of our deposit agreement. The deposit agreement provides that, upon receipt of notice of any meeting of holders of our common shares, the
depositary bank will, as soon as practicable thereafter if requested by us in writing, mail to ADS holders the notice of the meeting sent by us, voting instruction forms and a statement as to the manner in which instructions may be given by the
holders.

ADS holders will not generally be able to exercise voting rights attaching to the deposited securities on an individual basis.
Under the deposit agreement, the voting rights attaching to the deposited securities must be exercised as to all matters subject to a vote of shareholders collectively in the same manner, except in the case of an election of directors and
supervisors. The election of our directors and supervisors is by means of cumulative voting. In the event the depositary does not receive voting instructions from ADS holders in accordance with the deposit agreement, our chairman or his or her
designee will be entitled to vote the common shares represented by the ADSs in the manner he or she deems appropriate at his or her discretion, which may not be in your interest.

We may from time to time distribute rights to our shareholders, including rights to acquire our securities. Under the deposit agreement, the depositary will not offer you those rights unless the distribution to ADS
holders of both the rights and any related securities are either registered under the U.S. Securities Act of 1933, as amended, or the Securities Act, or exempt from registration under the Securities Act. We are under no obligation to file a
registration statement with respect to any such rights or securities or to endeavor to cause such a registration statement to be declared effective. Moreover, we may not be able to establish an exemption from registration under the Securities Act.
Accordingly, you may be unable to participate in our rights offerings and may experience dilution in your holdings.

If the depositary is
unable to sell rights that are not exercised or not distributed or if the sale is not lawful or reasonably practicable, it will allow the rights to lapse, in which case you will receive no value for these rights.

Your ability to convert proceeds received from your ownership of ADSs
depends on existing and future exchange control regulations of the Republic of China. Under the current laws of the Republic of China, an ADS holder or the depositary, without obtaining further approvals from the Central Bank of the Republic of
China (Taiwan) or any other governmental authority or agency of the Republic of China, may convert NT dollars into other currencies, including U.S. dollars, in respect of:



the proceeds of the sale of common shares represented by ADSs or received as share dividends with respect to the common shares and deposited into the depositary
receipt facility; and



any cash dividends or distributions received from the common shares represented by ADSs.

In addition, the depositary may also convert into NT dollars incoming payments for purchases of common shares for deposit in the depositary receipt
facility against the creation of additional ADSs. If you withdraw the common shares underlying your ADSs and become a holder of our common shares, you may convert into NT dollars subscription payments for rights offerings. The depositary may be
required to obtain foreign exchange approval from the Central Bank of the Republic of China (Taiwan) on a payment-by-payment basis for conversion from NT dollars into foreign currencies of the proceeds from the sale of subscription rights of new
common shares. Although it is expected that the Central Bank of the Republic of China (Taiwan) will grant approval as a routine matter, required approvals may not be obtained in a timely manner, or at all.

Under the Republic of China Foreign Exchange Control Law, the Executive Yuan of the Republic of China may, without prior notice but subject to subsequent
legislative approval rendered within ten days from such imposition, impose foreign exchange controls or other restrictions in the event of, among other things, a material change in domestic or international economic conditions which might threaten
the stability of the domestic economy in Taiwan.

If
you are a non-Republic of China person and wish to withdraw common shares represented by your ADSs from our ADS facility and hold those common shares, you are required under the current laws and regulations of the Republic of China to appoint an
agent, also referred to as a tax guarantor, in the Republic of China for filing tax returns and making tax payment. A tax guarantor must meet certain qualifications set by the Ministry of Finance of the Republic of China and, upon appointment,
becomes a guarantor of your Republic of China tax obligations. If you wish to repatriate profits derived from the sale of withdrawn common shares or cash dividends or interest on funds derived from the withdrawn common shares, you will be required
to submit evidence of your appointment of a tax guarantor and the approval of the appointment by the Republic of China tax authorities. You may not be able to appoint and obtain approval for a tax guarantor in a timely manner.

In addition, under the current laws of the Republic of China, you will be required to be registered as a foreign investor with the Taiwan Stock Exchange
for making investments in the Republic of China securities market prior to your withdrawal and holding of common shares represented by the ADSs. You will be required to appoint a local agent in Taiwan to, among other things, open a securities
trading account with a local securities brokerage firm and a bank account to remit funds, exercise shareholders rights and perform other functions as holders of ADSs may designate. You must also appoint a local bank to act as custodian for
handling confirmation and settlement of trades, safekeeping of securities and cash proceeds and reporting and declaration of information. Without the relevant registration and appointment of the local agent and custodian and the opening of a
securities trading account and bank account, you will not be able to hold, subsequently sell or otherwise transfer our common shares withdrawn from the ADSs facilities on the Taiwan Stock Exchange.

Each year, we announce guidance for the current fiscal year prepared in accordance with ROC GAAP and the requirements of the Taiwan Stock Exchange. These
projections are based on a number of estimates and assumptions and are inherently subject to significant uncertainties and contingencies, including the risks factors described in this annual report. These projections are not prepared with a view
towards compliance with published guidelines of the SEC, the U.S. Public Company Accounting Oversight Board or generally accepted accounting principles and, accordingly, you should not rely on this information. In particular, projections are
forward-looking statements that are necessarily speculative in nature, and it can be expected that one or more of the estimates on which the projections were based will not materialize or will vary significantly from actual results, and such
variances will likely increase over time.

Our legal and commercial name is Chunghwa Telecom Co., Ltd. Our common shares have been listed on the Taiwan Stock Exchange under the number
2412 since October 27, 2000 and our ADSs have been listed on the New York Stock Exchange under the symbol CHT since July 17, 2003. Our principal executive offices are located at 21-3 Hsinyi Road, Section 1,
Taipei, Taiwan, Republic of China, and our telephone number is (886) 2-2344-5488. Our website address is http://www.cht.com.tw. The information on our website does not form a part of this annual report.

We were established as a company on July 1, 1996 as a result of the separation of the business and regulatory functions of the Directorate General
of Telecommunications. We were privatized in August 2005.

We are the largest telecommunications service provider in Taiwan and one of the
largest in Asia in terms of revenues. As an integrated telecommunications service provider, our principal services include:



fixed line services, including local, domestic long distance and international long distance telephone services;

As our traditional fixed line business has matured and new technologies have become available, we have pursued new growth opportunities in the cellular
and internet and data services markets. We are focusing on enhancing our leading position in each of our principal lines of business, and expanding into new lines of business such as third generation, or 3G, cellular services. We enjoy leading
positions across a number of areas:



we are Taiwans largest provider of fixed line services in terms of both revenues and subscribers;



we are Taiwans largest cellular service provider in terms of both revenues and subscribers;



we are Taiwans largest broadband internet access provider as well as Taiwans largest internet service provider in terms of both revenues and
subscribers; and



we are also a leading player in the data communications market in Taiwan.

In 2006, our revenues were NT$186.3 billion (US$5.7 billion), our net income was NT$42.1 billion (US$1.3 billion) and our net income per share was
NT$4.34 (US$0.13).

In 2006, we incurred capital expenditures totaling NT$27.7 billion (US$0.8 billion), of which 64.7% was related to
wireline equipment, 34.0% was related to cellular equipment and 1.3% was related to other items. See Item 5. Operating and Financial Review and ProspectsB. Liquidity and Capital ResourcesCapital Expenditures for a discussion
of our capital expenditures.

We believe that we are well positioned to take advantage of growth opportunities in the telecommunications market in Taiwan as new technologies evolve. In particular, we have maintained our leading market share in
cellular and internet and data services since the opening of the Taiwan telecommunications market to competition in June 2001. Furthermore, we have enjoyed greater flexibility in making purchasing and other business decisions after we were
privatized in August 2005. In addition, our responsiveness to market conditions has been enhanced by the shortening in May 2002 of the approval period for primary tariff adjustments and promotional packages from 40 to 14 days.

We believe that further deregulation and market liberalization will continue to drive the growth of the overall market for telecommunications services in
Taiwan, as well as the development of new products and services. We expect to benefit from additional opportunities as the telecommunications market in Taiwan continues to grow.

We believe that our primary competitive strengths are:



our position as the only integrated, full-service telecommunications provider in Taiwan, and



our capital resources and technology, which we believe we can build on to expand our leading position in the growing cellular and internet and data services
markets, including through our continued construction of a 3G cellular network, fiber in the loop broadband access services, our IP-based MOD services and our rollout of VoIP services.

We are the largest telecommunications service provider in Taiwan with a leading position in local, domestic long distance and international long distance
telephone services, wireless services and internet and data services.

Broad range of communications products and services. We
believe that our ability to provide an attractive and comprehensive range of telecommunications services uniquely positions us to provide bundled and value-added services to our business and residential customers. In addition, we are able to offer
innovative bundled services and tariff packages to meet the specific needs of our customers.

Broad network coverage. The breadth of
our network and our ownership of the so called last mile infrastructure in Taiwan, which comprises the connection between the local telephone service providers switching centers to the end-users buildings or homes, provide us
with access to existing and potential customers and creates a platform for expanding our services. As of December 31, 2006, substantially all of our installed telephone lines are capable of delivering ADSL services. In addition, our cellular
services network provides nationwide coverage. Our large cellular spectrum allocation together with our network of 8,597 base stations position us well for the continued expansion of our cellular services in Taiwan.

Brand awareness, distribution channels and customer service. Our principal brands Chunghwa Telecom and HiNet have a
reputation for quality, reliability and technology. In particular, we are the leading internet service provider in Taiwan through HiNet. We serve our large and well-established customer base through our extensive customer service network in Taiwan,
including 24 operations offices, 322 service centers, 121 exclusive services stores and six integrated call centers. We also offer comprehensive and high-quality point of sale and after sale services, and we provide web-based customer services.
Moreover, our extensive sales and distribution channels help us attract additional customers and develop new business opportunities. In the Readers Digest Super Brands Award 2005, we stood out and won Platinum Award of Telecom Company in
Taiwan. We were also awarded Best Managed Company and Best Commitment to Strong Dividends in Taiwan by Finance Asia in 2006. In January 2007, the Standard & Poors Ratings Services raised our long-term foreign
currency credit rating to AA from AA- and removed us from CreditWatch, where it was placed with positive implications.

Operational expertise. Our management and employees have extensive operating experience and
technical knowledge, which we believe cannot be easily replicated by competitors. We also believe we will continue to attract and retain high quality employees.

Comprehensive customer billing infrastructure. As Taiwans leading telecommunications services provider, we have extensive resources and infrastructure relating to billing services. In particular, we
issue, in the aggregate, approximately 16 million invoices, including integrated bills, every month. We intend to continue taking advantage of this unique attribute by offering bill collection services to internet content providers and other
entities that lack the necessary resources and infrastructure for effective customer billing.

Established position in growing markets.
Revenues from our cellular and internet and data services have increased from 55.8% of revenues in 2003 to 64.1% in 2006. We expect our cellular and internet and data services to continue to be the key drivers of our future growth. With our
leading market share, we enjoy substantial economies of scale in equipment procurement as well as the marketing of our products and services.

Strong capital structure. We believe we have greater financial resources than other telecommunications operators in Taiwan. In particular, our relatively low debt-to-equity capital structure, together with our high levels of cash and
operating cash flows, provides us with the flexibility and resources to invest in capital intensive and growing businesses. In particular, we continue to invest in broadband internet protocol networks, fiber-optic networks, and 3G cellular
communications networks and services. We also have begun making investments in or acquiring other companies which provide complementary telecommunications and internet-related services to further expand our business and offer new products and
services.

Advanced network technology. Since 2003, we have developed and upgraded our existing infrastructure for both mobile and
fixed line networks. We developed a high-speed internet protocol backbone network and expanded the coverage of our ADSL network. In 2007, we launched a long-term next generation network construction project that will upgrade the local fixed line
networks to high-speed packet-based digital networks with fiber in the loop. Our investment in network infrastructure places us in a position to capture a significant share of the internet and high-speed data transmission market.

Research and development expertise. We employ over 1,187 research professionals and engineers whose principal focus is to develop advanced network
services and operations support systems and to build selected core technologies. In 2006, our research and development expenses, excluding depreciation and amortization, accounted for 1.5% of our revenues. We believe our focus on research and
development will allow us to efficiently develop and deploy new technologies and services ahead of our competitors.

Taiwan has one of the highest fixed line penetration rates in Asia and has also experienced rapid adoption of wireless communications and internet
services, including broadband access services. We believe that telecommunications services will evolve over the coming years, driven by a number of technological innovations. We also believe that the convergence of communications technologies will
provide a significant competitive advantage to integrated telecommunications service providers that are able to design and construct sophisticated and scalable networks capable of serving as a common platform for a broad range of services.

Our key strategic objectives are to maintain our position as a leading integrated telecommunications services provider in Taiwan and to
enhance our leadership position in growing markets, such as cellular and internet and data markets, including broadband access services and value-added services.

Our core strengths are the management of telecommunication networks and the provision of services over these networks. We currently operate several
networks linked by a core backbone infrastructure consisting of public switched telephone, cellular, ADSL and internet protocol networks. Our strategy for each network differs depending on the market dynamics and future growth prospects of services
delivered over these networks. In general, we endeavor to maintain our strong market position in each of our business lines and seek to expand the scope of our business beyond network services by offering value-added services to generate growth and
new opportunities.

Fixed line: Our strategy is to maintain our position as the market leader in fixed line
communications. In December 2006, we launched value-added services for the local telephone market, such as personal ring back tone. We also seek to enhance customer loyalty by promoting virtual private network and information communication systems
integration services targeted at our corporate customers. In January 2007, we launched a long-term project to create our next generation network that will upgrade the local fixed line networks to high-speed packed-based digital networks with fiber
in the loop. We expect our entire fixed line network to be eventually based on a fully integrated IP telephony system. We also plan to launch phone-to-phone voice VoIP after the National Communications Commission authorizes the 070 prefix for our
phone-to-phone VoIP service.

Cellular: Our strategy for our existing 2G cellular services, which uses the GSM standard, is
to continue to expand service offerings that take advantage of our strong customer base and extensive network coverage. In particular, we will focus on increasing our average revenue per subscriber by expanding our post-paid subscriber base and
promoting increased use of wireless value-added services, such as our emome mobile internet service, Java games, ring back tone services and video streaming. Furthermore, we launched our 3G cellular service based on a wideband code
division multiple access, or WCDMA, technology on July 26, 2005 and launched 3.5G services on September 12, 2006. Our strategy with respect to our 3G cellular service includes the following initiatives:



taking advantage of our ability to provide services using either the GSM or WCDMA standards and offer seamless service to customers with dual mode handsets, which
enable our customers to enjoy the benefits of network coverage while retaining their GSM cellular phone number. In order to meet the demand from our customers for high-speed wireless data access, we adopted high-speed downlink packet access
technology and continued developing third-generation cellular technology;



encouraging our high-end customers, who are more likely to demand wireless internet services with higher data speed access capabilities, to use our 3G and 3.5G
services by offering attractive service packages;



converging fixed line and cellular services to provide customers with access to personalized information through personal computers, personal digital assistants or
cellular handsets; and

Internet and data: Our strategy for internet and data services is to continue to build on the success of our HiNet internet services and ADSL
access services. We seek to complement the governments plan to grow Taiwans broadband subscriber base to 6 million subscribers by the end of 2007. We are the leading provider of broadband internet access in Taiwan, with a
significant market share as of December 31, 2006. We have successfully migrated many of our customers from low-speed to higher-speed internet access services. Approximately 62.5% of our broadband customers subscribe for downlink speeds of over
2 megabits per second, and the average downlink speed of our internet subscribers, defined as the total downlink speed subscribed divided by the total number of subscribers, increased from 0.6 Mbps as of December 31, 2002 to 2.56 Mbps as of
December 31, 2006. We are developing new media to provide both higher-speed access as well as attractive

content to our customers. We are continuing our build-out of fiber-to-the-building infrastructure, and continually enhancing our internet value-added
services, such as online gaming, internet music, internet banking and internet protocol video services, including multimedia on demand, or MOD, and hiChannel. We will launch VoIP services, after the National Communications Commission authorizes the
070 prefix for our phone-to-phone VoIP service.

Bundled services: We believe bundled services are effective in encouraging usage
and enhancing customer loyalty. We intend to increase our offerings for bundled services. In particular, we believe we are uniquely positioned to provide our customers with fully integrated solutions across fixed line, cellular and internet
platforms. Our Friends and Family service, which offers customers preferential rates, has attracted over 1.86 million mobile phone subscribers. In addition, we provide a wide range of bundled services customized to meet the needs of
our corporate customers, such as integrated network management services, secure internet services and 3G mobile office.

Quality of service is critical in attracting and retaining customers and enhancing our long-term
profitability. In order to continually enhance and improve the quality of our services, we have, in addition to the quality assurance function of our regular operating units, established a number of dedicated task forces to monitor our network
performance. Our senior management sets our quality evaluation criteria and regularly reviews the quality of our performance.

In order to
ensure that our quality of service will translate into strong customer loyalty, we plan to continue to focus on and invest in the provision of a full range of services that emphasize customer care from the point of sale onward. For example, we have
extended the focus of our corporate customer services from major accounts to include small and medium enterprises and on January 2007 established our Enterprise Business Group. Our Enterprise Business Group is staffed by approximately 1,200
professionals and offers packaged and customized services, customer-oriented solutions and integrated information and communications services. We have completed the integration of our call centers, all of which can now be reached by calling a single
number 123. We offer 24-hour customer service, including the handling of service and billing inquiries with the assistance of an Interactive Voice Response, or IVR, system. We also offer consolidated billing for our customers who use
multiple services. We began to provide an e-bill service option to our customers in August 2005. Moreover, we have put in place processes to enhance bill collection and improve the quality of our billing services. To improve the quality of our
customer services, we implemented a customer relationship management system, which encompass, among other things, a customer complaint system, a business information database for the use of our call centers, and a data mining system to enhance our
sales and market analysis efforts.

We have historically been focused, and will continue to focus, on cost control, particularly in the areas of network efficiencies and personnel costs. We
expect to be able to further improve our operational efficiency and cost structure by migrating to more advanced networks and sophisticated operational support systems, and efficiently managing our workforce.

Capital expenditures. Our long-term goal is to optimize our capital expenditures by focusing on investing in innovative products and services with
attractive return profiles. We have commenced a project for gradually upgrading our entire public switched telephone network to a next-generation network. Next-generation internet protocol switches will have substantially more capacity and greater
upgrade flexibility, and should result in savings from a reduced number of switching centers, and related property, materials and personnel costs. We have also devoted resources toward the expansion of our 3G cellular network and the continuing
build-out of our fiber in the loop infrastructure.

Personnel costs. We seek to improve our operational efficiency by reducing our
personnel costs. For example, we offered a number of voluntary retirement programs between July 1, 2003 and April 30, 2006 which

resulted in reductions of 3,712 employees. On the other hand, we also hired more than 593 new employees after privatization. In 2006, we further aligned our
organizational structure by integrating various operating units and departments. We will also continue to reallocate our personnel from traditional fixed line services to our growing businesses and to our marketing and customer services departments,
as well as exploring outsourcing opportunities where we deem appropriate. In 2007, we also plan to offer another preferential voluntary retirement plan for our employees.

We plan to expand our
business in high growth areas, such as interactive multimedia broadband services, content delivery services and value-added services, through alliances, acquisitions and investments. We believe that our experience, operational scale and large
subscriber base make us an attractive ally for other service providers.

Alliances. We have formed and will continue to pursue
alliances with information content providers, multimedia service platform providers and customer premises equipment providers to diversify our business operations and enhance our service offerings. As of the date of this annual report, we have
collaborated with more than 500 information content providers, more than 60 customer premises equipment providers, more than 6 internet service providers. We have signed cooperation memorandums with Microsoft and Intel to develop digital home
services.

Acquisitions. We have focused our acquisition strategy on making acquisitions of companies that we believe to be
complementary to our long-term strategic goals. During 2006, we acquired a 70% equity interest in Chief Telecom, a Type II operator and wholesaler of VoIP international voice traffic. This acquisition will complement our current telecommunications
offerings by expanding our capacity. In order to facilitate any future overseas acquisitions, we have established New Prospect Investments Holdings Ltd. and Prime Asia Investments Group Ltd. in March 2006, which are wholly owned holding companies
incorporated in the British Virgin Islands that operate as investment companies.

Investments. After the privatization, we have
focused our investment strategy on the development of new business and the increase of our operation efficiency. We formed Chunghwa International Yellow Pages Corporation and invested a 30% stake in a content provider, Spring House Entertainment
Inc. to help develop the content industry in Taiwan. In January 2007, we became a 31.3% shareholder of a mobile distributor, Senao International, by way of a public tender offer. Senao International is our largest cellular phone distributor with a
significant market share of the total market in Taiwan. We expect that our investment in Senao will increase our competitiveness in the cellular business, and we expect to take a larger share of the cellular phone distribution market.

Going forward, we may consider making other equity investments and acquisitions that we believe are complementary to our business and other strategic
goals. Our future investment will be aimed at expanding our business scale, making better use of our research and development resources and increasing our revenues through investing in online value-added services and digital content provision,
technology development, distribution channels and wireless communication. We expect to expand the scope of our international investments from regional to global and plan on focusing on emerging markets and other high-growth enterprises while
carefully evaluating the risks involved.

We are committed to maximizing shareholder value and intend to maintain our high dividend payout policy. We have historically maintained a conservative
capital structure and we were in a net cash position as of March 31, 2007. Following our privatization, we have more flexibility to implement capital management initiatives, including possible repurchases of our outstanding common shares and
increases in our leverage through debt financing. We bought back 192,000,000 shares between February 10, 2006 and April 9, 2006 and cancelled those shares on June 30, 2006.

The provision of fixed line services is one of our principal business activities. We are the largest provider of local, domestic long distance and international long distance telephone services in Taiwan. We also
provide interconnection with our fixed line network to other cellular and fixed line operators. Since June 2001, three new operators have begun offering fixed line services. Our revenues from fixed line services were NT$72.1 billion, or
approximately 38.9% of our revenues, in 2004, NT$66.3 billion, or approximately 35.9% of our revenues, in 2005, and NT$62.9 billion, or approximately 33.8% of our revenues, in 2006. Owing primarily to the expansion of our broadband and cellular
services, we expect that revenues from our fixed line business will continue to decline as a percentage of our total revenues.

We provide local telephone services to over 13.2 million subscribers in Taiwan. Our fixed
line network reaches virtually all homes and businesses in Taiwan. Revenues from local telephone services comprised

approximately 24.3%, 22.1% and 20.9% of our revenues in 2004, 2005 and 2006, respectively. Approximately 75.2% of our local telephone subscribers as of
December 31, 2006 were residential customers, accounting for approximately 60.5% of our local telephone revenues in 2006. We are currently the leader of the local telephone service market, with an average market share of approximately 97.9%,
97.4% and 97.4% in 2004, 2005 and 2006, respectively.

Data from the Department of Population, Ministry of the Interior, Republic of China.

Demand for local subscriber lines has historically been driven by population growth. In each of 2004 and 2005, fixed line subscriber growth slowed compared to prior periods, primarily due to market saturation and
competition. In 2006, the number of fixed line subscribers decreased by 1% compared to 2005, primarily due to an increase in the number of cancellations of fixed line service.

Calls to our HiNet service, which are recorded as part of our internet and data services, are not included in our local call minutes or revenues.

Minutes from local calls have declined as non-HiNet narrowband subscribers migrate to broadband internet services, which do not require dial-up telephone
access. This decline was also due to traffic migration to broadband and cellular services. As a result of our promotion in 2005 and 2006 of lower speed ADSL services, we have experienced that some non-HiNet dial-up customers migrated to ADSL
service, which has also contributed to a continued decline of minutes from local calls. However, we believe the rate of migration of traffic from fixed line services to broadband and cellular services is slowing.

We charge our local telephone service subscribers a monthly fee and a usage fee. We also charge separate fees for some value-added services. The monthly
fees for our primary tariff plans are NT$70 with a deductible on usage fees of NT$25 for residential customers and NT$295 for business customers. Our primary peak time usage fee is NT$1.6 for three minutes or NT$2.7 for ten minutes, depending on the
tariff plan selected by the subscriber, and our off-peak usage fee is NT$1.0 for ten minutes. Our usage fees are the same for residential and business customers.

Average per minute usage charges increased from NT$0.68 per minute in 2004 to NT$0.7 per minute in
2005 and NT$0.72 per minute in 2006. The increases were primarily due to a decline in demand for our discounted internet tariff packages as a result of a migration of non-HiNet dial-up subscribers to our ADSL services.

Part of our competitive strategy is to offer customers innovative products and services intended to both secure customer loyalty and enhance revenues. In
particular, our value-added services are designed to increase our call revenues by increasing the number of calls our customers make and by receiving fees for usage of the value-added services. These services include call waiting, caller
identification, call forwarding, three-party calls, ring back tone and voicemail.

We provide domestic long distance telephone services in Taiwan. Revenues from domestic long distance telephone services comprised approximately 6.4%, 5.9%
and 5.3% of our revenues in 2004, 2005 and 2006, respectively. Our average market share in the domestic long distance market was 86.4%, 84.7% and 83.6% in 2004, 2005 and 2006, respectively. Residential customers accounted for approximately 61.3% of
our domestic long distance revenues in 2006.

All domestic long distance calls, regardless of the distance between the calling parties, have the
same tariff. We changed the unit of billing from a per-minute basis to a per-second basis effective February 1, 1999. In addition, we reduced our peak hour domestic long distance rate in April 2001 from NT$0.045 per second to our current rate
of NT$0.035 per second. Our current domestic long distance rate for off peak hours is NT$0.025 per second. The rates for both peak hours and off peak hours are the same for residential and business customers. Our average domestic long distance usage
charge per minute remained flat between 2004, 2005 and 2006.

We provide so-called intelligent network services over our domestic long distance network,
including toll free calling, universal number, televoting, premium rate service and virtual private networks. We also focus on offering our customers an increasing number of value-added services and flexible tariff packages.

International Long Distance Telephone

We
provide international long distance telephone services in Taiwan. Revenues from international long distance telephone services comprised approximately 8.2%, 7.9% and 7.6% of our revenues in 2004, 2005 and 2006, respectively. Residential customers
generated approximately 33.0% of our international long distance revenues during 2006. In addition, we provide wholesale international long distance services to international simple resale operators who do not possess their own telephone network or
infrastructure.

Since fixed line services have been open for competition since 2001, we expect competition in this line of business will
continue to intensify. We believe other fixed line operators consider the international long distance market to be their primary focus. Our average market share of the international long distance market was approximately 61.3%, 57.8% and 58.3% in
2004, 2005 and 2006, respectively. Our market share increased in 2006 primarily because of a slight increase in our sales of wholesale minutes. Our international long distance services consist primarily of international direct dial services and our
discounted Super eCall services, which we introduced in April 2000. Under Super eCall, we use VoIP technology through international dedicated circuits which connect to our major correspondent carriers that route calls internationally.
Super eCall customers are offered rates that are approximately 30% lower than those for our international direct dial service. Calls made over Super eCall represented approximately 7.2% and 7.8% of our total outgoing international traffic in 2005
and 2006, respectively.

We commenced the wholesale of international long distance minutes to licensed international resale operators and
other international carriers in 2001. International resale operators require a fixed line operator in Taiwan to complete their long distance telephone services originating in Taiwan. In addition, other international carriers often find it less
expensive to route international calls through Taiwan. These resale operators and carriers purchase from us large numbers of minutes at discounted rates. Our international long distance wholesale business has grown rapidly since its introduction. In
2004, 2005 and 2006, we sold 595.4 million, 781.9 million and 1,041.5 million of wholesale outgoing minutes, which represented approximately 32.1%, 39.0% and 46.5% of our total outgoing international long distance minutes,
respectively. Revenues from the wholesale of international long distance minutes increased by approximately 28.7% from NT$1,124 million in 2005 to NT$1,447 million in 2006 As the international long distance market becomes more competitive, we
believe the wholesale business will allow us to generate increases in international minutes without accelerating the decline in international long distance rates in the more profitable retail segment.

International calls to and from our top five destinations represented approximately 60.2% our international long distance call traffic in 2006.

The following table shows the percentage of total outgoing and incoming international long distance minutes for our top five outgoing
destinations in 2006.

Total outgoing international long distance minutes increased by 8.0% from 2004 to 2005 and by
11.7% from 2005 to 2006, primarily due to promotions and increased wholesale minutes. Our incoming call volume slightly decreased by 0.2% from 2004 to 2005 due to increased competition resulting from lower priced calls offered by our competitors,
which reduced our incoming international call volume and increased by 5.0% from 2005 to 2006 due to active expansion of international wholesale incoming call services through overseas points of presence.

Outgoing calls made by customers in Taiwan and by customers from foreign destinations using Taiwan direct service are billed in accordance with our
international long distance rate schedule for the destination called. Rates vary depending on the time of day at which a call is placed. Customers are billed on a per minute basis for Super eCall services, whereas customers are billed on a six
second unit basis for international direct dial services.

Tariffs for international long distance calls have generally been declining worldwide and we
expect this trend to continue. We do not expect the increase in international call traffic to fully offset the decline in tariffs. In anticipation of new competition, we substantially reduced our international tariffs by an average of 37% in April
2001 to defend our business and market share. In addition, we offered our customers significant promotional packages and discounts during off-peak hours in 2004, 2005 and 2006 to maintain their loyalty. In particular, we increased the discounts
offered to our high-usage international long distance customers in each of these three years.

We pay for the use of networks of carriers
in foreign destinations for outgoing international calls and receive payments from foreign carriers for the use of our network for incoming international calls. Traditionally, these payments have been made pursuant to settlement arrangements under
the general auspices of the International Telecommunications Union. Settlement payments are generally denominated in U.S. dollars and are made on a net basis.

The following table sets forth information with respect to our gross settlement receipts and payments during the periods indicated.

Our payments on an aggregate basis to international carriers have been more than our receipts from these
carriers, primarily because our customers outgoing minutes exceeded incoming minutes. As international settlement rates have fallen, our international settlement receipts and our international settlement payments have both declined.

In order to compete more effectively in the international long distance market, we have implemented innovative and customized discount
calling plans and marketing campaigns directed at high-usage business customers. We also continue to promote our intelligent network services, including international virtual private networks, international toll free calling and calling card
services, and our international long distance minutes wholesale business. We also plan to launch phone-to-phone voice VoIP after the National Communications Commission authorizes the 070 prefix for our phone-to-phone VoIP service. We plan to target
specific customers for these services and offer bundled services to increase customer retention in the competitive business environment.

Cellular service, is one of our principal business activities. We are Taiwans largest provider of cellular services
in terms of both revenues and subscribers. In 2004, we generated revenues of NT$70.3 billion, or approximately 38.0% of our revenues, from cellular services. In 2005, we generated revenues of NT$73.0 billion, or approximately 39.5% of our revenues,
from cellular services. In 2006, we generated revenues of NT$73.0 billion (US$2.3 billion), or approximately 39.2% of our revenues, from cellular services.

As the market for cellular
services has continued to expand, we have experienced substantial growth in our cellular customer base. We are the largest cellular operator in Taiwan in terms of revenues and number of subscribers. We had 8.49 million cellular subscribers, for
a market share of approximately 36.5% of total 2G cellular subscribers and approximately 35.7% of total 2G cellular services revenues in Taiwan, as of December 31, 2006. Revenues from cellular services comprised approximately 38.0%, 39.5% and
39.2% of our revenues in 2004, 2005 and 2006, respectively. Mobile data revenues as a percentage of total cellular revenues were 3.3%, 4.4% and 5.7% for the years ended December 31, 2004, 2005 and 2006, respectively.

We offer digital cellular service through our dual band GSM network. We are one of the three national licensed providers of GSM services. We have been
allocated 15 MHz in the 900 MHz frequency band and 11.25 MHz in the 1800 MHz frequency band for GSM services and general packet-switched radio services, or GPRS, and 15 MHz paired spectrum plus 5 MHz unpaired spectrum in the 2 GHz frequency band for
3G cellular services. This is the largest frequency spectrum allocation to any cellular operator in Taiwan. In February 2002, the Ministry of Transportation and Communications granted 3G cellular services concessions to five companies, including us.
In March 2002, we paid NT$10.2 billion to the government for our concession. Our 3G cellular

services license is valid to December 31, 2018. In July 2005, we launched our 3G cellular telephone services using WCDMA technology. We also offer the
largest international roaming network among Taiwan cellular service providers. In particular, our 2G subscribers have access to 312 networks in 164 countries through our GSM service roaming network and 126 networks in 69 countries through our GPRS
roaming network. In addition, our 3G service system includes 37 networks in 22 counties.

As of December 31, 2006, we had
approximately 12,234 cellular base stations (including both GSM base stations and 3G cellular base stations) covering substantially all of Taiwans population. We use these base stations to support both our GSM network and our GPRS network. In
2006, we also selectively upgraded 82 base stations in downtown Taipei, Taiwan Taoyuan International Airport and certain industrial parks areas with HSDPA capability. We will continue this process of implementing HSDPA upgrades in the following five
major areas in Taiwan: Taipei City, Taipei County, Taoyuan County, Taichung City and Kaohsiung City.

The cellular market in Taiwan has grown rapidly since the liberalization of the market in 1997. Total
cellular subscribers in Taiwan has reached approximately 23.2 million as of December 31, 2006. Cellular penetration was approximately 101.6% on the same date. We expect the subscriber growth to continue to slow as a result of market
saturation. In addition, the overall cellular services market experienced a slowdown in terms of revenue in 2006. We believe that any future growth in the number of cellular subscribers will depend largely upon continuing improvements in wireless
technologies and wireless data applications and the availability of advanced cellular handsets.

We began offering prepaid card services in
October 2000. As of December 31, 2006, we had approximately 0.6 million prepaid customers representing approximately 7.5% of our total cellular subscribers. Prepaid customers do not pay monthly fees but pay a higher usage charge on a per
second basis. Once the prepayment has been fully utilized, a prepaid customer can make additional prepayments to continue the services. Alternatively, the customer may convert to become a post-paid customer while retaining the same telephone number.

We offer handset incentives to third party dealers when new subscribers agree to sign a two-year service contract with us or when existing
subscribers renew their contracts with us for a period of two years. We generally offer incentives on handsets equipped with more advanced data functions to promote the expansion of our GPRS and 3G cellular services. In 2006, the average handset
incentives we offered was NT$2,631 per subscriber up from NT$2,380 per subscriber in 2005 primarily due to an increase in the number of subsidized 3G customers. We expect the level of our average handset incentives to slightly decline in the
foreseeable future, with a decrease in incentives for handsets generally offset by higher incentives for 3G handsets.

Traffic growth has
also been strong as pricing has declined and the number of post-paid subscribers have increased. We have also experienced a significant increase in the number of short messaging service messages sent by our subscribers, which continued to have a
positive impact on traffic volume. The average minutes of usage per subscriber rose in 2004 because of a decline in prepaid customers as a percentage of total cellular customers, primarily as a result of accelerated closing of inactive prepaid
customer accounts. In contrast, the average minutes of usage per subscriber increased in 2005 because of a decrease in the number of prepaid customers. However, the average minutes of usage per subscriber increased in 2006 because of low pricing
packages, such as the Energy Plan which have stimulated usage.

Our tariffs for post-paid cellular subscribers primarily
consist of usage fees and monthly fees. When our subscribers are outside Taiwan, they pay roaming charges plus international long distance charges and, where applicable, local charges in roaming destinations. We charge a flat fee per transaction for
our short messaging service and a fee per packet for our GPRS based on the volume of data transmitted. We also offer discounts on usage fees for calls made between our cellular subscribers to encourage subscription to our cellular service. Our 3G
service also provides a monthly flat rate service to our customers using our 3G service for internet purposes.

The decrease in the number
of our prepaid subscribers in 2005 was primarily the result of our increased attention to closing inactive accounts. Our average revenue per subscriber per month increased from NT$712 in 2004 to NT$744 in 2005, primarily due to an increase in the
number of postpaid subscribers and an increase in the revenues of cellular value-added services. In 2006, average revenue per subscriber further decreased to NT$731 due to price cuts in SMS, or short message service, reduction of the tariff for
mobile calls to fixed-line numbers in 2005 and 3G promotion programs during 2006. In order to continue to increase average revenue per subscriber reduce the negative impact caused by the April 2007 GSM price adjustment, we intend to continue
introducing new value-added services and promote our 3G and 3.5G and wireless internet services.

In addition to our basic cellular
services, we also offer a broad range of value-added telecommunications and information services. In August 2001, we introduced a platform of integrated cellular value added services under the brand name emome. Our emome
services offer a broad range of value-added services, including financial information, transaction services, emergency services access numbers, directory information, time, weather and traffic reports. In addition, we have launched other cellular
value-added services, such as JAVA

We have experienced continued growth in our internet and data services. Our internet and data
revenues represented approximately 21.2%, 22.8% and 24.9% of our revenues in 2004, 2005 and 2006, respectively. We provide:

We have maintained
our leading market position despite a highly competitive market with over 181 internet service providers in Taiwan. We expect the competitive conditions currently prevailing in the internet service provider market to continue to intensify.

Customers can access HiNet through various technologies. We provide narrowband dial-up internet access through connections based on
standard telephone modems. We provide broadband internet access through connections based on ADSL and our fiber-to-the-building technology. As of December 31, 2006, approximately 79.5%, or 3.1 million, of subscribers who access the
internet through our ADSL are our HiNet subscribers, and we expect this ratio to increase as a result of recent promotions to attract dial-up customers to upgrade to broadband internet access.

We are the largest broadband internet access provider in Taiwan in terms of subscribers. We began providing our ADSL service in August 1999 and had
approximately 3.9 million subscribers as of December 31, 2006. Our market share of Taiwans broadband market was approximately 83.0%, 85.3% and 85.5% in 2004, 2005 and 2006, respectively. Our ADSL service allows for transmission of
data at high access rates and offers high-speed broadband internet access services. We also provide ADSL services to other internet service providers that do not have their own network infrastructure. By the end of 2006, the total number of our FTTB
customers reached approximately 185,000. In addition, 179,621 of the subscribers who access the internet through FTTB are Hinet subscribers. As of December 31, 2006, approximately 4.2% of subscribers who access the internet through our FTTB
were also HiNet subscribers, and we expect this ratio to increase as a result of recent promotions to attract ADSL and dial-up customers to upgrade to FTTB internet access.

Average downlink speed is calculated by dividing the total downlink speed subscribed by the total number of subscribers as of the relevant date.

Our ADSL service offers downlink speeds that range from 256 kilobits per second to 12 megabits per second and uplink speeds that range from 64 kilobits
per second to 1 megabit per second. In December 2001, we began providing symmetrical digital service with uplink and downlink speeds of 512 kilobits per second. After our promotions in 2004 to increase customer access speeds, including our
promotions for subscribers to upgrade to higher-speed access, the average uplink and downlink speeds of our subscribers have increased substantially. As of December 31, 2005, approximately 59% of our subscribers had subscribed for downlink
speeds of over

2Mbps per second and our average downlink speed was 2.14 Mbps. As of December 31, 2006, over 62.5% of our subscribers had subscribed for downlink
speeds of over 2 Mbps and our average downlink speed was 2.56 Mbps. Our FTTB service offers downlink speeds of 10 megabit per second and uplink speeds of 2 megabit per second.

We have experienced limited competition in the ADSL service market because other fixed line operators and cable operators have not established a
nationwide network infrastructure to provide this service.

Our revenues from providing internet access are generated from installation
fees, monthly subscription fees and usage fees from fixed line telephone calls made to access HiNet, which are recorded as internet services revenues rather than as fixed line revenues. Usage fees from fixed line telephone calls made to access
internet service providers other than HiNet are recorded as local fixed line revenues.

Charges for our HiNet dial-up service include a
monthly fee entitling the subscriber to a fixed number of minutes of service, with an additional charge per minute when the fixed number of minutes is exceeded. Alternatively, we offer our subscribers an unlimited number of minutes for a fixed
monthly fee. Charges for our ADSL service include one-time installation charges and monthly subscription fees. These charges vary based on connection speed.

Our average revenues per
subscriber have declined over the last three years due to increasing competition. In addition, we were required by the regulatory authority at that time, the Directorate General of Telecommunications, to decrease our tariffs by an average of 24% in
June 2004. However, we expect our average revenue per subscriber for broadband services to decline more gradually going forward, as subscribers migrate towards more expensive, higher bandwidth internet services.

Our HiNet portal at
www.hinet.net provides value-added services to our subscribers, such as network security, Blog, travel, gaming, e-learning, financial information, music, video, anti-virus and links to other portals. We charge fees for some of these services.
We also receive commissions for transactions completed on

some of these other portals. Our broadband internet portal at www.hichannel.hinet.net offers online entertainment services through the internet. In
particular, our HiNet broadband (ADSL and FTTB) customers can access music, television programs, movies and other multi-media content on demand. We charge access fees for some of this content. We expect the revenues generated from these value-added
services to grow as a percentage of our total internet and data services revenues. The information contained in our HiNet portal and broadband internet portal is not a part of this annual report. Our internet value-added services revenues as a
percentage of total internet revenues were 5.8%, 6.9% and 6.4% in 2004, 2005 and 2006, respectively.

We launched our wireless local area network service in May 2002. As of December 31, 2006, we had a total of approximately 30,262
residential and business customers that lease our access points. In addition, we have established 1,009 hot spots in public areas, such as airports and international convention centers, where individuals can access our wireless local area network.

We are the leading provider of domestic leased line services in Taiwan. We are also a leading provider of overseas leased line services. Leased line services involve offering exclusive lines that allow point-to-point
connection for voice and data traffic. Leased lines are used by business customers to assemble their own private networks and by telecommunications service providers to establish networks to offer telecommunications services.

We provide data transmission services to major corporate customers in Taiwan. We also provide leased lines to other cellular and fixed line service
operators for interconnection with our fixed line network and for connection within their networks. Since August 2001, licenses have been awarded to four undersea cable operators to engage in leased line services. Demand for high-speed data
transmission services has been growing rapidly, as a result of growing consumer demand and lower tariffs due to increased competition. In particular, the total bandwidth of our lines leased decreased by 3.3% over the two years ended
December 31, 2006.

The following table shows the bandwidth of lines leased to third parties as of each of the dates indicated.

Rental fees for local leased lines are generally based on transmission speed while domestic long
distance and international long distance leased line rental fees are generally based on transmission speed and distance.

We continue to experience a decline in rental fees for all of our leased line products. The decline in
rental fees since 2000 has been substantial, particularly for international leased lines, partly as a result of competition from new international leased line service providers. In response, we continue to implement marketing and service campaigns
to retain our high-value corporate customers.

We provide other telecommunications services, including MOD services, satellite services, telephone directories, corporate solution services and billing
handling services and paging services. In 2004, we generated NT$3.5 billion, or approximately 1.9% of our revenues. In 2005, we generated NT$3.2 billion or approximately 1.8% of our revenues, from these various other telecommunications services. In
2006, we generated NT$4.1 billion, or approximately 2.1% of our revenues, from these various other telecommunications services. We also lease real estate owned by us to third parties.

We launched our multimedia on demand, or MOD, service in Taipei County and Keelung City in March 2004. We expanded this service to cover 13 counties and
cities of Taiwan by the end of 2006. Using video streaming technology through a set top box that connects to our ADSLs, our customers can access TV programs and other services. We had 33 broadcasting channels, and over 1,600 on-demand programs and
served approximately 249,203 subscribers as of December 31, 2006. In addition, our video-on-demand service provides movies, e-learning and music programs for home entertainment. We also plan to introduce popular channels and bundle them with
other pay channels in order to enhance our service content and satisfy our customers needs.

We are a 50% owner of the ST-1 telecommunications satellite. Singapore Telecommunications Ltd. owns the remaining 50%. ST-1 was launched on
August 26, 1998 and began commercial operations on December 1, 1998. We lease out transponder capacity on ST-1 and provide satellite lease circuits. In addition, we have two satellite communication centers that enable us to provide
satellite value-added services and back up systems for use in major emergencies. We also provide satellite services to Southeast Asia.

We are the largest provider of classified advertising directory and associated products and services in Taiwan with over 60 years of experience in publishing and distributing telephone directories to households and
businesses in Taiwan. Our yearly circulation is approximately 6.3 million copies. To address the needs of advertisers and users for multiple platforms of directory search, we offer buyers and sellers related directory products and services in
print, through online directories and by operator-assisted search services. In addition, we established Chunghwa International Yellow Pages Corporation in 2007, changing previous paper search business into a more advanced search service combining
electronic yellow page and telephone voice cross-platform services.

We offered nationwide and regional paging services in Taiwan. In addition to traditional paging services, we offered a broad range of wireless information
services, including stock quotes on our InterMessenger service, weather information, news and agricultural information. We had approximately 35,520 and 23,620 paging subscribers as of December 31, 2005 and 2006.

We provide interconnection of our
fixed line network with other cellular operators and, since July 2001, with other fixed line operators.

The following table sets forth our
interconnection fee revenues and costs for the periods indicated. These revenues and costs are included, depending on the nature of the call made, in local, domestic long distance services or cellular revenues and expenses, respectively.

Currently, tariffs for telephone calls between our fixed line subscribers and cellular subscribers
of other cellular operators are set by the cellular operators. The cellular operators pay us interconnection fees based on minutes of usage, regardless of who initiated the call. The former regulatory authority, the Directorate General of
Telecommunications, and the current regulatory authority, the National Communications Commission, has consulted with the public regarding a change to the regulation that would allow us to set and collect tariffs for telephone calls made by our fixed
line subscribers to cellular subscribers of other cellular operators. For such calls, cellular operators will no longer pay us interconnection fees, but we will be required to pay them termination charges. On September 5, 2006, the National
Communications Commission announced that it proposes to make changes to the collection structure in two phases. In phase one, fixed line operators other than us would be able to set and collect tariffs for telephone calls made by their fixed line
subscribers to cellular subscribers of other cellular operators. In phase two, we would be allowed to set and collect tariffs for telephone calls initiated by our subscribers if (i) the market share of our local telephone services falls to and
under 90% or (ii) the transfer acceptance rate of our number portability service and the acceptance rate for leasing out local loop both reach 85% every month for six consecutive months and we share our telecom switching centers with other
fixed line operators. If and when such proposal may be implemented is uncertain.

In the interim, the former regulatory authority, the Directorate General of Telecommunications has
approved, effective January 2004, an interconnection rate of NT$0.59 per minute for calls initiated by cellular subscribers, and NT$0.814 per minute for calls initiated by fixed line subscribers. The interconnection rate between our fixed line
subscribers and other fixed line subscribers is approximately NT$0.32 per minute. The interconnection rate between our cellular subscribers and other cellular subscribers is approximately NT$2.15 per minute.

All interconnections by the networks of cellular operators and other fixed line operators with our fixed line network are made through dedicated lines
that these operators lease from us. We record the revenue for these leased lines as part of our internet and data revenues.

We expect an
increase in interconnection revenue due to an increase in traffic between different fixed line networks as a result of the competition from other fixed line operators.

In accordance with governmental regulations, the contracts governing our interconnection arrangements must specifically address a number of prescribed issues. For example, our interconnection charge should reflect our
cost with respect to the network elements used. In addition, cost increases are subject to approval by the regulatory authorities. We expect that our interconnection contracts will generally be reviewed annually, although we may also enter into
long-term contracts.

In order to retain and expand our large customer base and to encourage our customers to increase
their use of our services and products, we continue to focus our marketing strategy on the following areas.



Services, Products and Bundled Offerings. We continually develop new value-added services and products, and bundle our services and products based on
different market segments, with the aim of increasing our high-usage customers and enhancing customer loyalty.



Pricing and Promotions. We design flexible pricing packages that allow customers to select structures best tailored to their usage patterns, and design
special promotional packages to encourage usage. For example, we have provided our Friends and Family and Energy Plan promotion package to attract cellular subscribers.



Distribution Channels. We seek to facilitate customer subscription by adding more service points. In addition, we seek to broaden our distribution
reach by strengthening our cross-industry alliances and marketing relationships. Furthermore, we seek to expand our sales channels by implementation of a sales agent system. We have also developed staff incentive programs to better motivate our
sales staff.



Business Customers. We have expanded our customer focus to include small- and medium-sized enterprises in addition to large corporations. We seek to serve
the needs of large corporate customers by devoting a project manager or project engineer to service these customers. These account managers are responsible for developing customized solutions and tariff packages to meet the specific needs of
our customers. We continually update and expand our service offerings so that we can remain a one-stop telecommunications services provider to our corporate customers and provide for all of their telecommunications needs. Our dedicated local teams
serve the needs of small- and medium-sized enterprises. These teams also use our data bank to identify and target potential clients for promoting our e-commerce and cellular services. In addition, we help our corporate customers improve their
efficiency and competitiveness by creating information systems for them.



Advertising. We are committed to further strengthening the Chunghwa Telecom brand and image as well as strengthening and expanding market recognition
of our specialized product brands, such as HiNet and emome. We plan to leverage our leading market position and status to strengthen the overall advantage of our product brands.

Our marketing department at our corporate headquarters in Taipei is responsible for central business planning and formulating our marketing strategies and objectives. We have six business divisions, each of which has
its own marketing department that is responsible for business and marketing planning.

We also have 24 operations offices, 322 service
centers and 121 exclusive service stores located throughout Taiwan that are responsible for operations, sales and customer service in their local areas.

We believe our reputation for quality customer service has helped us attract new
customers and maintain customer loyalty. We regularly survey our customers to improve our service and better understand market demand and subscriber preferences, and seek to develop products and services accordingly.

We provide the following services to our customers:



24-hour customer service and technical support through our service centers, call centers and website;



English billing documents available upon request;



free of charge itemized billing for international and domestic long distance calls;

We
purchase most of our network equipment from well-known international suppliers. As part of the purchase contract, these suppliers deliver and install the equipment for us. We also purchase from local suppliers a variety of components such as
transmission lines, switches, telephone sets and radio transmitters.

Approximately 15,086 of our employees were engaged in network
infrastructure development, maintenance, operation and planning as of December 31, 2006.

Our internet protocol broadband backbone network consists of a core network and edge networks. We completed the construction of our
high-speed internet protocol backbone network at the end of 2006 with 14 sets of 640 Gbps gigabit switch routers for the core network and more than 54 sets of 320 Gbps and 80 Gbps gigabit switch routers for the edge networks. We believe this network
will enable us to meet the increasing demand for broadband access and broadband multimedia services. Moreover, this network will also serve as the backbone for our 3G cellular services and VoIP services.

Between 1999 and 2002, we made significant progress in the upgrading of our plesiochronous digital
hierarchy network transmission facilities to synchronous digital hierarchy network transmission facilities. Plesiochronous digital hierarchy is the traditional technology for voice network transmission systems. Synchronous digital hierarchy
architecture is an advanced technology that allows for instantaneous rerouting and eliminates downtime in the event of a fiber cut. In addition, synchronous digital hierarchy offers better reliability and performance for optical fiber transmissions
at a lower operating cost. In December 2002 we installed synchronous transport module 64 multiplexer and 10 gigabit capacity 32-wavelength dense wavelength division multiplexing equipment on our long-haul backbone network. Our synchronous transport
module 64 multiplexer can multiplex several low speed signals into a 10 gigabit per second high-speed signal. Dense wavelength division multiplexing equipment uses a technology that puts data from different sources together on an optical fiber with
each signal carried on its own separate wavelength. Both synchronous transport module 64 multiplexer and dense wavelength division multiplexing equipment can increase our network capacity. Furthermore, between 2003 and 2006, we deployed twenty-five
32-wavelength optical add-drop multiplexer rings in Taipei, Taichung, Tainan and Kaohsiung, metropolitan areas in order to provide new data services such as gigabit Ethernet, fiber channel, 2.5 gigabit packet over synchronous digital hierarchy and
10 gigabit Ethernet. To meet the demand for broadband services, we completed the deployment of a next generation synchronous digital hierarchy network in June 2005. The next generation synchronous digital hierarchy network can provide gigabit
Ethernet over synchronous digital hierarchy service.

Based on the transmission network described above, we launched connection circuit
service of 10 gigabit packet over synchronous digital hierarchy and 10 gigabit Ethernet to the governments Taiwan Advanced Research and Education Network in 2003.

As part of our strategic focus on the internet and data markets, our local loop connections use ADSL technology. This enables us to deliver high-speed internet, multimedia and other data services to our customers.
Substantially all of our installed telephone lines are capable of delivering ADSL services. As of December 31, 2006, we have constructed approximately 5.13 million lines of ADSL and had 3.85 million ADSL users. In addition, the
ethernet-based fiber to the building system is also introduced into our access network to provide broadband services, such as MOD, high speed internet access and virtual private network, or VPN.

As of December 31, 2006, we have constructed approximately 300,000 ports of VDSL and had 165,000 users. Our FTTB (VDSL) can offer high-speed
broadband Internet access rates up to 100 Mbps.

Domestic telecommunications network. Our domestic public switched telephone network consists of 19 message areas connected by a long
distance network. As of December 31, 2006, we had 66 long distance exchanges, which are interconnection points between our telecommunications network.

We currently have intelligent networks installed over our public switched telephone networks for our domestic long distance and international networks, as well as a local intelligent network in the Taipei, Taichung
and Kaohsiung metropolitan areas. Our intelligent network is designed to facilitate the use of value-added services by providing more information about calls and allowing greater management of those calls.

As of December 31, 2006, our domestic network included 17.4 million installed telephone lines, and reached virtually all homes and businesses
in Taiwan.

International network. Our international transmission infrastructure consists of both submarine cable and
satellite transmission systems, which link our national network directly to 103 telecommunications service providers in 59 international destinations.

International calls are routed between Taiwan and international destinations through one of our two international switching centers, one located in Taipei and the other in Kaohsiung. Each center had two international
gateway switches. In total, we had a trunks capacity of 85,040 channels as of December 31, 2006.

We provide cellular services based on the GSM network standards. We have dual band 900 MHz and
1800 MHz frequency spectrums for our GSM services. In addition, we have installed an intelligent network on our cellular services network infrastructure to enable us to provide prepaid services as well as a wide range of advanced call features and
value-added services. We have also installed wireless application protocol gateways on our cellular services network that enable us to provide wireless application protocol services. We began providing cellular communications services based on the
GPRS network standards in August 2001, using emome as the portal name.

As our subscriber base has continued to grow, we have increased the capacity of our intelligent network
to more than 1.5 million subscribers. We also completed a system expansion of our cellular services network to accommodate more than 8.5 million subscribers (including 2 million GPRS subscribers) at the end of 2003. We have GPRS and
15 MHz paired spectrum plus 5 MHz unpaired spectrum in the 2 GHz frequency band for our 3G cellular services. In preparation for the launch of 3G cellular services, we contracted with Nokia Corporation to provide the core network, radio access
network, service network, transmission network and maintenance network for approximately NT$12 billion over three years. As of December 31, 2006, we have completed the construction of approximately 3,637 third generation base stations with a
network capacity of 2.4 million lines. Our 3G cellular network is comprised of 3,637 base stations, with a capacity of 2.4 million lines upon completion of contract. We launched our 3G cellular services on July 26, 2005. As of
December 31, 2006, we had approximately 943,000 3G cellular services customers.

In September of 2006, we also selectively upgraded
our third generation cellular network to provide HSDPA capabilities, with 82 base stations in downtown Taipei, Taiwan Taoyuan International Airport and certain industrial parks where the mobile internet usage is higher. We also plan to extend the
HSDPA coverage to three metropolitan areas, Taipei, Taichung and Kaohsiung, in 2007, with data rates starting from the current 384kbps to the future 1.8Mbps, 3.6Mbps or higher, to attract more high average revenue per user, or ARPU, users.

HiNet, our internet service provider, has the largest internet access network in Taiwan, with 35 points of presence, approximately
3,496 dial-up ports, approximately 4,535,050 broadband remote access server ports and a backbone bandwidth of approximately 424 gigabits per second as of December 31, 2006. We plan to increase HiNets points of presence and backbone
bandwidth to approximately 599 gigabits per second by the end of 2007.

HiNets total international connection bandwidth is 51.3
gigabits per second as of December 31, 2006. As we expect that internet traffic flows to and from the United States will continue to increase, we plan to expand our bandwidth to the United States. We also plan to increase our links to other
countries, including Japan, Korea, Hong Kong, Singapore, Mainland China, Malaysia and Australia.

We operate leased line networks on both a managed and unmanaged basis. In addition, we operate a number of switched digital networks
used principally for the provision of packet-switched, frame relay, asynchronous transfer mode technology and a multi protocol label switching internet protocol virtual private network. We have completed the construction of a digital cross connect
system for provisioning and managing voice-grade data services throughout Taiwan with a total of 50 nodes. As of December 31, 2006, we had 2,623 frame relay ports, 5,441 X.25 ports, 7,867 asynchronous transfer mode ports and approximately
50,000 multi protocol label switching internet protocol virtual private network virtual ports.

Our data networks support a variety of transmission technologies, including X.25 protocol, frame relay
and asynchronous transfer mode technology. We have also built up our HiLink virtual private network that combines internet protocol and asynchronous transfer mode technologies. The advantage of a HiLink virtual private network based on multi
protocol label switching technology is that it can carry different classes of services, such as video, voice and data together to provide services with various qualities of service, high performance transmission and fast forward solution in
an enhanced security network. A HiLink virtual private network can be accessed by an ADSL and can include built-in mechanisms that can deal with overlapping internet protocol addresses. Therefore, the network potentially is less costly and requires
less management for business applications.

We are the largest fixed line service provider in Taiwan, with a market share of approximately 97.4% in
terms of subscribers for local telephone services, approximately 83.6% in terms of traffic for domestic long distance telephone services and approximately 58.3% in terms of traffic for international long distance telephone services in 2006. Three
new providers, namely, Taiwan Fixed Network, New Century Infocomm Tech. Co., Ltd. and Asia Pacific Broadband Telecom Co. Ltd., have provided fixed line services since June 2001. We believe these operators are primarily focused on international long
distance services. In addition, we anticipate that these operators will focus on corporate customers, which typically generate higher profit margins than residential customers. Since August 2001, four undersea cable services licenses have been
granted. These undersea cable operators, as well as internet service providers and international simple resale operators, have begun offering international leased line services to other fixed line operators, internet service providers and
international simple resale operators.

We are required by Republic of China regulations to provide number portability and unbundled local
loop access.

Our domestic long distance services compete with cellular services as people increasingly use cellular telephones. In
addition, our international long distance services compete with international long distance resale services and alternative mediums for making international calls, including VoIP technologies, such as those provided by Skype. One of our competitors
has sought an alliance with Taiwan Railway Administration to use its infrastructure to deliver telecommunications services. We believe that the fixed line competition in Taiwan will be primarily based on price, quality of service, network coverage
and customer services, such as call centers and unified billing.

There are currently three major GSM cellular operators in Taiwan, namely, Taiwan Mobile Co., Ltd., Far EasTone Telecommunications Co., Ltd. and us. Based
on data provided by the National Communications Commission, as of December 31, 2006, we were the largest cellular operator, with a 40.9% market share in terms of 2G subscribers. In addition, there are two new 3G cellular operators in Taiwan,
namely Asia Pacific Broadband Wireless Communications Inc. and Vibo Telecom Inc., as well as one personal handyphone system operator, First International Telecom. Furthermore, the government issued 12 mobile virtual network operator licenses to New
Century InfoComm Tech. Co., Ltd., KGEx.com, Hicall Telecom Co., Ltd., China Motion Telecom (Taiwan) Limited, Taiwan Fixed Network, 10net, INFOTECH International Corp., Network Telecommunication Co., Ltd., AURORA Telecom Corporation, ARCOA
Communication Co., Ltd., Chung-Hwa

Wideband Best Network and Chia Hsin Food & Synthetic Fiber Co., Ltd. which allow operators without a spectrum allocation to provide cellular
services by leasing the capacity and facilities of a cellular service network from a licensed cellular service provider. We may cooperate with other mobile virtual network operators in Taiwan in future. We compete in the wireless services market
primarily on the basis of price, quality of service, network reliability and attractiveness of service packages.

We are the largest provider of internet
services in Taiwan. As of December 31, 2006, we had a 61.2% share of the internet service market in terms of subscribers and a 85.5% share of the broadband internet access market in terms of subscribers. We compete in the internet and data
services market primarily on the basis of price, technology, speed of transmission, amount of bandwidth available for use, network coverage and value-added services.

Our properties consist mainly of land, land improvements and buildings located throughout
Taiwan. We have recently begun investing in real estate revitalization projects as part of our efforts to make more productive use of certain undeveloped or underdeveloped properties that we own. Our revitalization projects include the development
of high-tech residences, commercial offices and resorts. As of the date of this annual report, we have six such projects underway relating to properties in and around Taipei and other parts of Taiwan.

We do not carry comprehensive insurance
for our properties or any insurance for business disruptions. We do, however, maintain in-transit insurance for key materials, such as cables, equipment and equipment components. We also carry insurance for the ST-1 satellite while it is in orbit.
As part of our efforts to enhance our risk management capabilities, we have been assessing our equipment that requires the most time and cost to repair or replace, in order to determine whether and to what extent we should carry fire insurance for
such equipment.

A portion of the land that we used
during the period from July 1, 1996 to December 31, 2004 was co-owned by us and Taiwan Post Co., Ltd. (the former Chunghwa Post Co., Ltd, Directorate General of Postal Service). In accordance with the claims process in Taiwan, on
July 12, 2005, the Taiwan Taipei District Court sent a claim notice to us to reimburse Taiwan Post Co., Ltd. in the amount of $768 million for land usage compensation due to the portion of land usage area in excess of our ownership, along with
interest calculated at 5% interest rate from April 1, 2002 to the payment date. However, we believe that the computation used to derive the land usage compensation amount is inaccurate because most of the compensation amount has expired as a
result of the expiration clause. Therefore, we have filed an appeal at the Taiwan Taipei District Court. As of the date of this annual report, the case is still in the appeals process. While we cannot accurately predict the eventual resolution of
this litigation, we believe that the final outcome will not have a material adverse effect on our results of operations or our financial condition.

We are also involved in other litigation, arbitration or administrative proceedings in the ordinary course of our business. Although we cannot accurately predict the outcome of these matters, we do not expect any proceeding, if determined
adversely against us, to have a material adverse effect on our business, financial condition or results of operation.

We are a company limited by shares and incorporated under the Republic of China Company Law and the Statute of Chunghwa Telecom Co., Ltd. All of our
directors and executive officers, our supervisors and some of the experts named in this annual report are residents of Taiwan and a substantial portion of our assets and the assets of those persons are located in Taiwan. As a result, it may not be
possible for investors to effect service of process upon us or those persons outside of Taiwan, or to enforce against them judgments obtained in courts outside of Taiwan. We have been advised by our Republic of China counsel that in their opinion
any final judgment obtained against us in any court other than the courts of the Republic of China in connection with any legal suit or proceeding arising out of or relating to the ADSs will be enforced by the courts of the Republic of China without
further review of the merits only if the court of the Republic of China in which enforcement is sought is satisfied that:



the court rendering the judgment has jurisdiction over the subject matter according to the laws of the Republic of China;



the judgment and the court procedure resulting in the judgment are not contrary to the public order or good morals of the Republic of China;



if the judgment was rendered by default by the court rendering the judgment, we were served within a reasonable period of time in accordance with the laws and
regulations of the jurisdiction of the court or process was served on us with judicial assistance of the Republic of China; and



judgments at the courts of the Republic of China are recognized and enforceable in the court rendering the judgment on a reciprocal basis.

A party seeking to enforce a foreign judgment in the Republic of China would be required to obtain
foreign exchange approval from the Central Bank of the Republic of China (Taiwan) for the payment out of Taiwan of any amounts recovered in connection with the judgment denominated in a currency other than NT dollars if a conversion from NT dollars
to a foreign currency is involved.

Before March 1, 2006, the Taiwan telecommunications industry was subject to extensive regulation by
and under the supervision of the former competent authorities, the Ministry of Transportation and Communications and the Directorate General of Telecommunications pursuant to the provisions of the Telecommunications Act and various other
telecommunications laws and regulations, as well as regulations under various laws of general application. Since March 1, 2006, regulatory authority over the Taiwan telecommunications industry has been transferred from the Ministry of
Transportation and Communications and the Directorate General of Telecommunications to the National Communications Commission.

We were
subject to the Statute of Chunghwa Telecom Co., Ltd. prior to our privatization. Although we have been privatized, the Legislative Yuan has not yet abolished the Statute of Chunghwa Telecom Co., Ltd., and at this time, the Statute of Chunghwa
Telecom Co., Ltd. is still applicable to us.

Prior to March 1, 2006, we were under the supervision of the Ministry of Transportation and Communications and the Directorate General of Telecommunications. On March 1, 2006, the National Communications
Commission was formed in accordance with the National Communications Commission Organization Law, or Organization Law, which was intended to transfer regulatory authority over the Taiwan telecommunications industry from the Ministry of
Transportation and Communications and the Directorate General of Telecommunications to the National Communications Commission. The National Communications Commission is to be comprised of thirteen commissioners and is currently comprised of nine
commissioners who have been recommended by the government and opposition political parties in the Legislative Yuan, as well as recommended by the Executive Yuan and approved by the Legislative Yuan. However, the Executive Yuan considered the
composition of the National Communications Commission unconstitutional and petitioned the Grand Justices of the Republic of China, or the Grand Justices, to interpret the constitutionality of the formation of the National Communications Commission
and the procedure for nominating commissioners to serve on the National Communications Commission. On July 21, 2006, the Grand Justices rendered an interpretation and held that the relevant provisions under the Organization Law as to the
nomination procedures for the commissioners of the National Communications Commission were unconstitutional. However, the Grand Justices granted a grace period allowing such provisions of the Organization Law to remain in effect until
December 31, 2008. Consequently, the National Communications Commission will have the authority at least until the end of 2008.

In
accordance with the National Communications Commission Organization Law, the National Communications Commission is responsible for:

maintaining competition order in the telecommunication and broadcasting industries;



governing technical standards in connection with the safety of information communications;



managing and facilitating the resolution of disputes pertaining to the Taiwan telecommunications and broadcasting industries;



managing offshore matters relating to Taiwans telecommunications and broadcasting industries including matters of international cooperation;



managing funds allocated for the development of Taiwans telecommunications and broadcasting industries;



monitoring, investigating and determining matters in relating to Taiwans telecommunications and broadcasting industries;



enforcing restrictions under telecommunications and broadcasting laws and punishing violators; and



supervising other matters in relation to communications and media.

Prior to our privatization, in each fiscal year, the Legislative Yuan approved the annual budget prepared by us, as a state-owned enterprise, and the Ministry of Audit under the Control Yuan audited, and adjusted, our
consolidated financial statements, including our earnings and losses. Our annual budget is no longer subject to Legislative Yuan or Control Yuan approval or audit.

Under the Telecommunications Act, telecommunications service providers are classified into two categories:

Type I. Type I service providers are providers that install network infrastructure, such as network transmission, switching and auxiliary equipment
for the provision of telecommunications services. Type I

services include fixed line services such as local, domestic long distance and international long distance services, as well as interconnection, leased line,
ADSL and satellite services and wireless services such as cellular, including 3G cellular, paging, mobile data and trunked radio services.

Type II. Type II service providers are defined as all telecommunications service providers other than Type I service providers. Type II services are divided into special services and general services. Special services include simple
resale, VoIP international leased circuit and other services specified by the Ministry of Transportation and Communications before March 1, 2006 or by the National Communications Commission from March 1, 2006. General services include any
Type II service other than special services.

Until 1996, we were the sole provider of Type I services in Taiwan. In 1996, the government
opened the market for cellular, paging and trunked radio, mobile data and digital low power cordless telephone services. In 1998, the government opened the market for fixed line and mobile satellite services. In June 2001, the government granted
licenses to three operators for establishing fixed line services, thereby opening the market for fixed line services. Since August 2000, the government has permitted four undersea cable operators to engage in the undersea cable leased-circuit
business.

Commencing in 2007, the National Communications Commission began accepting applications for licenses to provide fixed line
services in March, June, September and December of each year. The National Communications Commission also announced that it would accept applications for fixed line services on a monthly basis beginning in 2008. There is no limit on the number of
fixed line licenses that they may decide to issue.

Type I service providers are
more closely regulated than Type II service providers. The government has broad powers to limit the number of providers and their business scope and to ensure that they meet their facilities roll-out obligations. Under the Telecommunications Act,
Type I service providers are subject to pre-licensing merit review of their business plans and tariff rates.

Before March 1, 2006,
licenses for Type I services were granted by the Ministry of Transportation and Communications through a three-step procedure. Applicants obtained a concession from the Ministry of Transportation and Communications. After obtaining a concession, the
applicant obtained a network construction permit and an assignment of spectrum, in the case of cellular telephone services and satellite services, from the Directorate General of Telecommunications or the Ministry of Transportation and
Communications prior to applying for a license. Upon completion of construction of its network and review by the Directorate General of Telecommunications, the applicant was granted a Type I license. The Ministry of Transportation and Communications
had the authority to grant Type I licenses for each of fixed line services, wireless services and satellite services. Type I licenses have different minimum paid-in capital requirements for applicants and varying durations depending on the
particular type of service.

Since March 1, 2006, the same procedure applies except that the licenses are granted by the National
Communications Commission.

The Telecommunications Act further authorizes the competent authority, now the National Communications
Commission to promulgate separate regulations governing each Type I service including the business scope of the Type I service provider, as well as the procedures and conditions for granting special permits and the length of the period of the
special permits of each Type I service. Each holder of a Type I license will pay a fee ranging from 0.5% to 2% of the annual revenues generated from the particular Type I service for which a license has been granted.

Fixed Line Services. Under the Telecommunications Act, the Fixed Network Regulations adopted by
the Ministry of Transportation and Communications continue to govern the issuance of fixed line service licenses and the business scope of fixed line providers. Fixed line service licenses are subdivided into the following categories:

local, domestic long distance and international long distance leased line services.

We conduct our fixed line services through a license for integrated services.

Licenses for local telephone and integrated services are valid for 25 years. Licenses for domestic long distance and international long distance
telephone services are valid for 20 years. Licenses for leased line services are valid for 15 years. The minimum paid-in capital requirement for integrated services providers and international undersea leased cable service providers is NT$40 billion
and NT$800 million, respectively. The minimum paid-in capital requirement for both domestic and international long distance telephone service providers is NT$2 billion. The minimum paid-in capital requirement for local telephone service providers is
NT$12 billion multiplied by the Local Network Operation Weights for the regions in which local network managerial rights have been granted to the service provider. The Local Network Operation Weights are calculated as the population of the region as
a proportion of the entire population of Taiwan and are announced by the competent authority every three years.

In March 2000, the
government granted three new concessions to fixed line services providers for integrated services. Recipients of these concessions are required to apply for a network construction permit to deploy broadband local access networks. Each recipient of
these concessions is required to have capacity for 150,000 subscribers before they are able to apply for a fixed line license to launch their proposed services. The three fixed line service providers have since obtained fixed line licenses and are
required to achieve capacity for one million subscribers by the sixth year following the date of the grant of the network construction permit awarded. Operators that applied for integrated service provider licenses after June 30, 2004 must
achieve a capacity for 400,000 subscribers, ports or a combination of both by the fourth year following the date of the grant of the network construction permit.

Wireless Services. Under the Telecommunications Act, the Wireless Regulations promulgated by the Ministry of Transportation and Communications before March 1, 2006 or by the National Communications
Commission from March 1, 2007 continue to govern the issuance of wireless services licenses and the business scope of wireless service providers. Wireless service licenses are subdivided into the following categories:



cellular services;



paging services;



mobile data services;



digital low-power cordless telephone services; and



trunked radio services.

Wireless
service licenses are granted to both regional and national service providers through review and bidding procedures.

Wireless services licenses for cellular and paging services are valid for 15 years, and licenses for
mobile data, digital low-power cordless telephone and trunked radio are valid for ten years. The minimum paid-in capital requirement for regional cellular service providers and national cellular service providers is NT$2 billion and NT$6 billion,
respectively.

We are licensed to provide cellular and paging services in Taiwan.

Third Generation Cellular Services. The Ministry of Transportation and Communications promulgated the Third Generation Mobile Telecommunications
Services Regulations on October 15, 2001 and these regulations were last amended on November 17, 2005. The regulations govern voice and non-voice telecommunications services provided using the spectrum assigned by the Ministry of
Transportation and Communications, and now governed by the National Communications Commission, that utilizes the IMT-2000 technical standards as announced by the International Telecommunications Union. Licenses for 3G cellular services were granted
by the Ministry of Transportation and Communications. We have received our 3G cellular services license, which is valid from May 26, 2005 to December 31, 2018.

Satellite Services. Under the Telecommunications Act, the Satellite Regulations promulgated by the Ministry of Transportation and Communications govern the issuance of satellite services licenses and the
business scope of satellite service providers. Satellite services licenses are subdivided into fixed satellite services licenses and mobile satellite services licenses.

The Telecommunications Act
was amended in 1996 to open the market for all Type II services. Under the Type II Services Regulations as last amended on November 15, 2005, Type II services are divided into special services and general services. Special services include
simple resale, VoIP, network telephone service of E.164 and non-E.164 user numbers (IP Phone Numbers), international leased circuit and other services previously specified by the Ministry of Transportation and Communications and now by the National
Communications Commission. General services include any Type II service other than special services. The policy for granting a Type II service license is as follows:



there is no limit on the number of licenses to be issued;



licenses were granted by the Directorate General of Telecommunications before March 1, 2006 and are now granted by the National Communications Commission; and



no bidding procedure is required.

We hold a license to operate all Type II services. Type II service licenses issued before November 15, 2005 are valid for ten years and may be renewed by application made two months prior to the expiration date. Type II service
licenses issued or renewed on or after November 15, 2005 are valid for three years and may be renewed during the period commencing two months prior to the expiration date. There is no minimum paid-in capital requirement for Type II service
providers. Our license to operate Type II services is included in our license to operate integrated services, and is valid from July 29, 2000 to July 28, 2025.

On December 27, 2005, the Ministry of Transportation and Communications promulgated regulations governing the fees payable for Type II licenses. Under these regulations, operators of simple resale or network
telephone services of E.164 or non-E.164 user numbers must pay an annual license fee equal to 1% of annual revenues generated from these services during the previous year. Type II service operators providing services

other than simple resale or network telephone services of E.164 or non-E.164 user numbers must pay license fees ranging from NT$6,000 to NT$150,000 depending
on their respective paid-in capitals. The regulations do not apply to integrated services providers who are permitted to provide Type II services without additional Type II Licenses. The annual license fee for an integrated services provider
operating Type II businesses is 1% of its annual revenues generated from its Type II services.

The Directorate General of
Telecommunications started to process the applications for allocating E.164 and non-E.164 user numbers (IP phone numbers) on November 15, 2005. A few operators, including our company, have applied for IP phone numbers. We believe after these
operators obtain the numbers and begin offering their services, competition in this area will become intense. We plan to provide VoIP service after we obtain IP phone numbers.

Under the Telecommunications Act, the regulations governing dominant telecommunications services providers apply only to Type I service providers. A Type
I service provider is deemed to be dominant if it meets any of the following criteria and was declared by the Ministry of Transportation and Communications or now the National Communications Commission as dominant:



controls key basic telecommunications infrastructure;



has dominant power over market price; or



has more than a 25% market share in terms of customers or revenues.

We have been declared by the former competent authority Ministry of Transportation and Communications as a dominant Type I service provider for fixed line and cellular services.

Under the Telecommunications Act, a dominant Type I service provider must not engage in the following activities:



directly or indirectly hinder a request for interconnection with its proprietary technology by other Type I service providers;



refuse to release to other Type I service providers the calculation methods of its interconnection fees and other relevant materials;



improperly determine, maintain or change its tariffs or means of services;



reject, without due cause, a request for leasing network components by other Type I service providers;



reject, without due cause, a request for leasing lines by other service providers or subscribers;



reject, without due cause, a request for negotiation or testing by other service providers or subscribers;



reject, without due cause, a request for negotiation for co-location by other service providers;



discriminate, without due cause, against other service providers or subscribers; or



abuse its position as a dominant provider, or engage in other unfair competition activities as determined by the regulatory authorities.

In addition, a dominant Type I service provider is subject to special regulations limiting its tariff changes.

In order to promote competition in the telecommunications market, and as part of the governments overall policy toward deregulation, the Telecommunications Act was amended in 1999 to abolish the former rate of
return system on tariff setting in favor of price cap regulation of Type I services.

Under the Regulations Governing Tariffs of Type I Service Providers promulgated and last amended by the
Ministry of Transportation and Communications on January 11, 2006, a dominant Type I service provider must submit its proposed adjustment in primary tariffs and promotional packages to the Directorate General of Telecommunications for onward
submission to the Ministry of Transportation and Communications or, from March 1, 2006, directly to the National Communications Commission from for approval at least 14 days prior to the date of the proposed tariff changes and announce such
change on media, website and business locations on the next day after the Ministry of Transportation and Communications or National Communications Commission grants the approval. The tariff change will come into effect seven days after the
announcement.

for fixed line international long distance telephone services: usage fees and leased line monthly rental fees;



for wireless services, including third generation cellular services: monthly rental fees and usage fees; and



other fees or tariffs announced by the Directorate General of Telecommunications before March 1, 2006 or by the National Communications Commission from
March 1, 2006.

In addition, a dominant Type I service provider is required to set wholesale prices for the
provision of its telecommunication services to other telecommunication enterprises. The wholesale prices set by a dominant Type I service provider may be the retail price less fees and expenses which need not be incurred, but shall not higher than
its promotional pricing. The Regulations Governing Tariffs of Type I Service Providers further prohibits a dominant Type I service provider from practising unfair competition against other telecommunication enterprises.

In comparison, all non-dominant Type I service providers are required to notify the Directorate General of Telecommunications or the National
Communications Commission from March 1, 2006 and the public of their proposed tariff adjustments seven days prior to the date of the proposed tariff change with respect to all tariffs. In addition, changes in tariffs charged by Type I service
providers (notwithstanding the type of their respective services) may not, in any event, be greater than the annual growth rate of the consumer price index in Taiwan adjusted by a set constant, which will be periodically determined and announced by
the National Communications Commission. For example, if:



the annual growth rate of the consumer price index in Taiwan minus the set constant is positive, the increased percentage of tariffs must not exceed such positive
figure;



the annual growth rate of the consumer price index in Taiwan minus the set constant is negative, the decreased percentage of tariffs must be at least the absolute
value of such negative figure, and the tariffs used in the given year must not be higher than the decreased tariff; and



the annual growth rate of the consumer price index in Taiwan minus the set constant equals to zero, no increase in tariffs is allowed to be made by any Type I
service providers.

In December 2006, the National Communications Commission announced that effective from April 1,
2007 to March 31, 2010:



the set constant to be applied to the tariff adjustment for leasing of ADSL under the fixed line integrated service and the local telephone service is the annual
growth rate of the consumer price index in Taiwan plus 5.35%;

the set constant to be applied to the tariff adjustment of call charges for call made from local telephones to the 900 MHZ and 1800 MHZ cellular services is the
annual growth rate of the consumer price index in Taiwan plus 4.88%;



the set constant to be applied to the tariff adjustment for the minimum monthly subscription fee charged for 900 MHZ and 1800 MHZ cellular services is the annual
growth rate of the consumer price index in Taiwan plus 4.88%;



the set constant to be applied to the tariff adjustment for prepaid phone card fees and other prepaid service fees charged for 900 MHZ and 1800 MHZ cellular
services is the annual growth rate of the consumer price index in Taiwan plus 4.88%; and



the set constant to be applied to the tariff adjustment for other services is equal to the annual growth rate of the consumer price index in Taiwan.

Type II service providers are free to establish their own tariff schemes, but are required to notify the Directorate
General of Telecommunications or, from March 1, 2006 the National Communications Commission and the public upon adoption and upon any subsequent adjustments.

The Telecommunications Act requires that a Type I service
provider, including one who concurrently offers Type II services, separately calculate the profits and losses for its different services and prohibits any cross-subsidization among services that will impede fair competition.

The Telecommunications Act requires all Type I service providers to allow other Type I service providers access to their networks. It further requires Type I service providers, within three months upon request by the other Type I service
provider, to reach an agreement on the relevant terms for the interconnection. Prices charged for interconnection must be based on cost. If the parties fail to reach an agreement within three months, the National Communications Commission may,
either at the request of the parties or on its own accord, arbitrate and determine the interconnection terms for the parties. According to the Administrative Rules for Network Interconnection Between Telecommunication Service Providers, the tariffs
for communications (except for international communications) between a cellular telecommunications network and a fixed line telecommunications network) shall be collected by the call-originating services provider from its subscribers pursuant to the
tariff schedules set by the cellular services provider, and the revenue or any uncollectible accounts from such tariffs shall go to the cellular services provider. In addition, tariffs for communications within cellular telecommunications networks
shall be collected by the call-originating services provider from its subscribers pursuant to the tariff schedules set by such provider, and the revenue or any uncollectible accounts from such tariffs shall be for the account of to the
call-originating services provider.

When a Type I service provider leases unbundled network components to another Type I service provider,
the parties are required to negotiate the rental fee. Unbundled network components include:

The
Telecommunications Act authorizes the Directorate General of Telecommunications or, from March 1, 2006, the National Communications Commission to issue rules and regulations pertaining to interconnection. Under the Administrative Rules for
Network Interconnection issued by the Directorate General of Telecommunications, as last amended on November 17, 2005, we, as a dominant Telecommunication service provider for fixed line and cellular services, are required to unbundle our
network and provide cost-based interconnection charges calculated with reference to the total element long-run incremental cost incurred by us. We are required to submit our proposed calculations of the total element long-run incremental cost to the
Directorate General of Telecommunications or, from March 1, 2006, the National Communications Commission, for its approval each year. Local loop unbundlings for both voice and data have been completed.

Under
the Telecommunications Act, when a Type I service provider cannot construct bottleneck facilities within a reasonable period of time or substitute those facilities by other available technologies, it may request for co-location on a fee basis from
the owner of the facilities located at the bottleneck of the relevant telecommunications network. The owner of the facilities so requested may not reject these requests without due cause. The Ministry of Transportation and Communications had the
authority, now held by the National Communications Commission, to prescribe facilities as bottleneck facilities, and has prescribed bridges, tunnels, lead-in tubes and telecommunications chambers located within buildings and horizontal and vertical
telecommunications cables and lines as bottleneck facilities in relation to fixed line telecommunications networks. The National Communications Commission made an announcement on December 21, 2006, defining the local loop as bottleneck
facilities.

The Ministry of Transportation and Communications previously and now the National Communications Commission allocates all telecommunications related frequencies primarily according to the standards set by the
International Telecommunications Union. The 900 MHz and 1,800 MHz frequency bands have been allocated for cellular applications. A total of 40 MHz spectrum around the 800 MHz frequency band and a total of 130 MHz of spectrum around the 2 GHz band
have been allocated for 3G cellular services.

Frequency allocation for fixed wireless platforms, such as wireless local loop and local
multipoint distribution services, has already been set. Only some bands of the spectrum made available for these services are completely clear and there is partial usage in all other bands. The cost of frequency usage will be based on quantity.

A Type I service provider may be required by the Ministry of Transportation and Communications previously and now the National Communications Commission under the Telecommunications Act, to provide universal
telecommunications services in remote or unprofitable areas. All Type I service providers and certain Type II service providers designated by the Ministry of Transportation and Communications previously and now the National Communications Commission
will be required to contribute a fixed portion of their annual revenues to a universal services fund. Such a fund will be used to compensate any losses and management fees incurred by the relevant Type I service provider in providing the universal
services. In April 2005, the Ministry of Transportation and Communications amended the Regulations on Telecommunications Universal Services, pursuant to which Type I service providers are required to provide universal telecommunications services and
contribute to the costs and expenses of providing such services on a pro rata basis according to their respective

revenues. The same regulation was further amended by the National Communications Commission in late 2006 to exclude certain services, such as coastline
station reporting for ship accidents, from the provision of universal telecommunications services and revise the scope of access to data communications services.

As a result of the liberalization of Taiwans telecommunications industry,
a Type I service provider, including a 3G cellular services provider, is required to provide its subscribers with equal access to the domestic and international long distance telephone services provided by other service providers. A Type I service
provider may provide equal access through pre-selection or call-by-call selection. Before July 1, 2005, all Type I service providers, including us, provide equal access only through call-by-call selection. When a subscriber makes a call using
call-by-call selection, such subscriber has the option to select a service provider by dialing the network identification prefix assigned to the service provider of his choice. This will result in the automatic selection of the preferred service
provider for the provision of relevant telecommunication services. Starting from July 1, 2005, all Type I service providers also provide equal access through pre-selection in Keelung City, Taipei City/County, Taichung City/County and Kaohsiung
City/County. Equal access through pre-selection is available throughout Taiwan since January 1, 2006. The pre-selection function allows any subscriber to select in advance a long distance or international service provider of his or her choice.
When such subscriber makes a call using this function, the communications network will automatically interconnect to the long distance or international network previously selected by such subscriber.

The
Ministry of Transportation and Communications has adopted principles on fixed line number portability to enable customers to migrate their local and toll free fixed line telephone numbers. Under these regulations, we are required to provide fixed
line number portability in seven major cities and counties in Taiwan upon the grant of the first fixed line license to a new entrant. We are also required to provide such number portability in other service areas no later than 181 days from the
grant of such license and upon six months advanced written notification received from the new fixed line service provider. Since May 2002, fixed line number portability has been made available to all customers in accordance with the then
prevailing Fixed Network Regulations.

In November 2003, the Directorate General of Telecommunications promulgated the Administration Rules
Governing Number Portability governing both fixed line and cellular services and the Fixed Network Regulations were revised to reflect such new regulation. Under the Administration Rules Governing Number Portability, which rules were amended on
September 22, 2005, subscribers may migrate their telephone numbers when changing Type I service providers. The number portability for wireless services commenced on October 15, 2005.

In December 2006, the
National Communications Commission defined the local loop as facilities at the bottleneck of telecommunications networks in accordance with the Regulations Governing Fixed Network Telecommunications Businesses. The National
Communications Commission further amended the Administrative Rules for Network Interconnection Between Telecommunication Service Providers in April 2007 which provides that we can only charge other local telephone service providers at cost for local
loop services instead of on the basis of commercial negotiations.

We have been declared by the former competent authority Ministry of Transportation and Communications as a dominant Type I service provider for fixed line
and cellular services. According to the Telecommunication Act, the Regulations Governing Fixed Network Telecommunications Businesses and the Administrative Rules for Network Interconnection between Telecommunication Service Providers, if any other
service provider requests for co-location, we must negotiate with them, unless otherwise provided by laws or regulations. In 2005, the other three Type I fixed line service providers, Asia Pacific Broadband Telecom, Taiwan Fixed Network and

New Century InfoComm Co., requested co-location for 12 point of interconnect, or POI, sites and one cable station. In 2006, after negotiations, we completed
all 12 POI sites and the one cable station. In addition, another Type I cellular service provider, Taiwan Mobile, also requested co-location for 15 POI sites. After negotiations, we completed 9 POI sites in 2006, with 6 other sites completed in
March 2007.

The laws of the Republic of China limit foreign ownership of our common shares. Prior to March 1, 2006, the Ministry of Transportation and Communications, as the competent authority under the Telecommunications Act, had the power to
prescribe the limits on foreign ownership of our common shares. After the formation of the National Communications Commission, on March 1, 2006, the National Communications Commission replaced the Ministry of Transportation and Communications
as the competent authority under the Telecommunications Act pursuant to the Organization Law. However, it is unclear whether the National Communications Commission (instead of the Ministry of Transportation and Communications) has the authority to
prescribe the limits of foreign ownership of our common shares. On July 19, 2006, the Ministry of Transportation and Communications increased our foreign ownership limitation from 40% to 49% pursuant to the Telecommunications Act. It is
currently unclear whether the Ministry of Transportation and Communications has such authority to increase our foreign ownership limitation. If it is determined that the Ministry of Transportation and Communications did not have such authority and
our foreign ownership is above 40%, we could be deemed in violation of the foreign ownership limitations and as a result we may be subject to monetary fines and our licenses to operate some of our businesses could be revoked. However, according to a
draft amendment to the Telecommunications Act proposed by the National Communications Commission on August 31, 2006, the power to prescribe the limits on foreign ownership of our shares under the Telecommunications Act is to remain with the
Ministry of Transportation and Communications.

Under the current Telecommunications Act, the Chairman of a Type I service provider is
required to be a citizen of the Republic of China.

According to the Administrative Fee Law promulgated in December 2002, central and local governments, government agencies and schools are empowered to
collect administrative fees from us and other telecommunications services providers for the telecommunications facilities built on public roads and properties. Under the Administrative Fee Law, Urban Road Act and Local Road Act, road authorities of
municipal governments may collect usage fees from users of local roads, including us, for establishing lines along with the local roads. The fee schedule is set up in the Standard for Usage Fees of Local Roads.

In addition, under the Public Road Law, as amended in July 2003, administrative authorities of public roads may collect usage fees from the users of
public roads. According to the Rules Governing Collection of Usage Fees on Public Roads, the relevant collection agencies, including agencies designated by the Ministry of Transportation and Communications and municipal governments, depending on the
types of public roads, may collect usage fees from users, including us, for establishing lines along with the public roads.

On the date
of our privatization, we were required to make termination payments in accordance with the pension payment determined under the Labor Standards Law plus six months salary and one months wages in lieu of prior notice of termination to our
employees who chose not to continue their employment. The government is responsible for paying the six months salary to our employees who chose not to continue their employment.

Upon the completion of our privatization, we were required to make a settlement payment to our employees
who chose to remain with us, based on their seniority and in accordance with the pension payment determined under the Labor Standards Law as if they have retired at the time of privatization. Those employees who remained with us and who are laid off
within five years after the completion of our privatization will be entitled to a payment equal to the pension benefit accrued from the date of our privatization to the date of termination, six months salary and one months wages
(including salary, bonuses, allowances and other regular payments) in lieu of prior notice of termination. The government has agreed to assume the cost of paying the six months salary to the laid-off employees.

The government will indemnify those employees who have suffered from any losses and damages due to our privatization, such as losses arising from change
of an insurance program.

Part of the funds realized from our privatization will be allocated to the Privatization Fund, and the rest of
the funds will go to the Treasury of the Republic of China. Indemnification payments by the government will be made from the Privatization Fund.

In light of the privatization of our company, the Executive Yuan, on
May 1, 2006, proposed a motion for the abolishment of the Statute of Chunghwa Telecom Co., Ltd. for legislative approval. We cannot determine when this motion will be approved by the Legislative Yuan. Under Republic of China law, the Statute of
Chunghwa Telecom Co., Ltd will continue in effect until the Legislative Yuan formally approves the motion and the President of the Republic of China pronounces the abolishment of the law.

While the continued application of the Statute of Chunghwa Telecom Co., Ltd. remains unclear and it may be abolished in the near future, under that statute we are required to obtain approval of the Ministry of
Transportation and Communications for:



the adoption of and any changes to our articles of incorporation and board of directors organization rules;



any changes to our authorized capital and any issuance of our common shares;

In accordance with the
Statute of Chunghwa Telecom Co., Ltd., our employees have rights to subscribe for not more than 10% of a new issuance of our common shares at favorable terms in accordance with subscription rules which were to be announced by the Ministry of
Transportation and Communications. However, no such rules were ever announced. In addition, under the Republic of China Company Law, employees of Republic of China companies have pre-emptive rights to subscribe for between 10-15% of any new issue of
shares by the company.

Our fixed line revenues are derived primarily from the provision of local, domestic long distance and international long distance telephone services. In
addition, we also derive fixed line revenues from providing interconnection services to other carriers. Our revenues from cellular services are principally derived from the provision of voice services and, to a lesser extent, from SMS and other data
services. Our revenues from internet and data services are generated principally from HiNet, our internet service provider, from our ADSL services, and from the provision of dedicated leased lines for our business customers and other operators.

The table below sets forth the revenues from our principal lines of business as a percentage of revenues for the periods indicated.

Beginning with the fiscal year ended December 31, 2006, we no longer combine cellular and paging services in one business segment. Instead, revenues from paging services are
included in Other. For this reason, revenues for 2004 and 2005 have been reclassified on a comparable basis.

Over the past
three years, the composition of our revenue base has undergone a significant change as a result of our strategy to diversify our revenues and focus on generating increased revenues from higher growth businesses, such as internet and data services.

Internet and data services have been our fastest growing sources of revenue over the last three years. Most of our increased revenues have
come from internet access services, with our ADSL services accounting for a significant portion of such increase. We launched our ADSL services in August 1999, and we had approximately 3.9 million subscribers as of December 31, 2006
Increasing internet penetration in Taiwan and higher data traffic have contributed to a significant increase in our revenues from internet and data services over this period. We believe that internet and data services will continue to generate an
increasing percentage of our revenues. Revenues from our local telephone and domestic long distance telephone and paging services have declined during this period, mainly due to traffic migration to cellular services. Revenues from our international
long distance services have also declined, as international long distance tariffs have declined worldwide. Revenues from our mobile phone services remained flat in 2006 and in 2005, but the percentage of mobile phone services in total revenue
declined in 2006 due to increasing market competition and the tariff reductions in SMS and calls from mobile phones to fixed-line numbers.

Three operators
in addition to us have been providing fixed line services in Taiwan since June 2001. We believe that these competitors are largely targeting business subscribers, which generally generate higher revenues per subscriber as compared with residential
customers. We are facing significant competition, particularly in the international long distance telephone services market, from these competitors.

Since August 2001, the Ministry of Transportation and Communications has awarded undersea cable service licenses to four additional operators. Moreover, in February 2002, the Ministry of Transportation and

Communications awarded five concessions to provide 3G cellular services. Two of these new concessions were awarded to new cellular operators. In addition,
the government issued six mobile virtual network operator licenses in 2004, and began to allow mobile number portability services in October 2005. As of the date of this annual report, there are 12 mobile virtual network operators. The increased
competition in the areas of fixed line, leased line and cellular services has led to, and may continue to lead to, further declines in our tariffs, which may result in a decrease in our revenues from these services. At the same time, the increased
competition has stimulated consumer demand for telecommunications services, with results including higher international telephone usage and increased international bandwidth demand. We seek to minimize loss of customers from the increased
competition by continuing to offer handset incentives, more competitive pricing packages, our Friends and Family packages and mobile virtual private networks for our corporate customers.

We adjust our tariffs and
offer promotional packages from time to time primarily in response to market conditions. We also from time to time are required to adjust our pricing in line with domestic regulations.

In July 2003, we reduced monthly rental fees for our ADSL services by an average of 16%.

In June 2004, we:



reduced monthly rental fees for our ADSL services by an average of 24%;



reduced the tariff for HiNet ADSL services by an average of 22%; and



reduced the short messaging service fee from NT$2 to NT$1.5 per message for messages sent between our customers and from NT$2.5 to NT$2 per message for messages
sent to users of other service providers.

In April 2005, we reduced monthly rental fees for part of our ADSL services by
an average of 2%. For downlink speeds of 256k services, the reduction rate was as high as 47%.

In June 2005, we reduced short messaging
service fees from NT$1.5 to NT$1.3 per message for messages sent between our customers and from NT$2 to NT$1.7 per message for messages sent to users of other service providers.

In December 2005, we reduced mobile dialing fees for calls to local telephone numbers by an average of 7%.

In December 2006, we began providing wholesale prices for the following services: ATM domestic leased lines, TWIX domestic leased lines and peering
bandwidth, domestic type I carriers, interconnection leased lines and other domestic leased lines, to facilitate the National Communications Commissions request that market leaders provide wholesale prices to Type I and Type II
telecommunications operators.

The National Communications Commission adopted a price reduction plan on December 21, 2006 that came
into effect on April 1, 2007, setting a 4.88% price reduction in the tariff for fixed-line to GSM mobile phone dialing, a 4.8875% price reduction in the GSM highest tariff package and a 5.2% price reduction in prepayment cards. The NCC also
requested us on April 1, 2007 to reduce the tariffs for ADSL service, and we are awaiting approval from the NCC on our plan to reduce the ADSL tariff by 5.35%. The price reduction plan also required us to stop collecting NT$5.0 monthly
maintenance fee from our fixed-line customers and a NT$70.0 fixed-line basic charge from our ADSL users who only use data services.

We
expect to continue to adjust tariffs and offer a variety of promotional packages from time to time in response to increasing competition and in order to take advantage of our pricing power from economies of scale. We may also be required to adjust
our pricing due to changes in domestic regulations.

In recent years, we have focused on modernizing and upgrading our cellular services network, and on developing our ADSL network, which enables
transmission of digital information at a high-bandwidth over existing telephone lines. In particular, we have enhanced our telecommunications services through:



the introduction of a VoIP exchange system in our long distance telephone network;



the implementation of a network modernization program, including a gradual transfer from our public switched telephone network to a system based on internet
protocol, to remain at the forefront of new technologies;

the expansion and upgrade of our cellular services network, including the rollout of GRPS; and



the construction of our 3G cellular services network.

As a result, we incurred aggregate capital expenditures of NT$105.7 billion over the period from January 1, 2003 to December 31, 2006

Our long-term goal is to optimize our capital expenditures by focusing on investing in innovative products and services with attractive return profiles.
We evaluate our investment opportunities by benchmarking them against internal return requirements. We are currently finalizing plans for the gradual upgrade of our entire public switched telephone network to a next-generation network.
Next-generation internet protocol switches will have substantially more capacity and greater upgrade flexibility, and should result in increased operational efficiencies from reduced switching centers, and related property, materials and personnel
costs. We have also devoted resources toward the effective rollout of our 3G cellular network and the continuing build-out of our fiber-to-the-building infrastructure.

Personnel expenses constitute a significant portion of our operating costs and expenses. In 2004, 2005 and 2006 personnel expenses represented 32.8%, 39.4% and 34.8% respectively, of our total operating costs and expenses, and pension costs
represented 11.3%, 7.8% and 7.1%, respectively, of our personnel expenses. The table below sets forth information regarding personnel expenses, depreciation and amortization and other operating costs and expenses in the aggregate and as a percentage
of our total operating costs and expenses for the periods indicated.

Does not include NT$129 million, NT$183 million and NT$142 million of pension costs associated with employees engaged in construction projects that were capitalized and not treated
as personnel expenses in 2004, 2005 and 2006, respectively.

The following table sets forth our personnel expenses (divided
into pension and non-pension portions) allocated by categories of operating costs and expenses:

At the time of our privatization, our then existing defined benefit pension obligations were
settled in full. After completion of our privatization, our continuing employees were deemed to have commenced employment as of the date our privatization was completed for seniority purposes under our pension plans in effect after privatization.
Under applicable Republic of China regulations, upon our privatization, the Ministry of Transportation and Communications assumed the obligation to make annuity payments to our employees who retired before our privatization. Under US GAAP
reporting, the portion of the pension obligations that was settled by the Ministry of Transportation and Communications, was represented by the difference between the accrued pension liabilities, the deferred pension cost and related deferred income
tax assets was accounted for as contributed capital and recorded under our stockholders equity as of August 12, 2005.

As of
December 31, 2006, we adopted SFAS 158 and recorded the under-funded status of our defined benefit pension plans as a liability with a corresponding offset, net of taxes, recorded in accumulated other comprehensive income within
stockholders equity.

We expect our pension costs for the fiscal year 2007 to be approximately NT$3.0 billion.

Increases in our costs and expenses in recent years were also attributable to purchases of our common shares by our employees at discounts. We recognize
compensation expenses when our employees purchase our common shares at discounts under the priority share subscription program. We recognized such compensation expenses in the amounts of NT$0.5 billion, NT$12.8 billion and NT$0.5 billion (US$15
million) in 2004, 2005 and 2006, respectively.

Under a program established pursuant to a regulation adopted by the Ministry of Transportation and
Communications, our employees were able to subscribe for up to approximately 476.9 million of our common shares from the Ministry of Transportation and Communications in offerings conducted by the Ministry of Transportation and Communications
prior to our privatization. As long as our employees agree not to transfer or pledge these shares for either two or three years, are eligible to receive a discount of 10% or 20%, respectively, from the offering price. Pursuant to a June 2005
amendment to the terms of this program, the majority of our employees who continued their employment with us after our privatization are also eligible to receive a 50% discount if they agree not to transfer or pledge the shares for four years.

At the time when we were privatized, the Ministry of Transportation and Communications implemented another stock subscription program,
allocating up to approximately 476.9 million common shares, or 4.9% of our then outstanding common shares, for a one-time subscription by our employees. Under this program, a majority of our employees will be eligible to receive a discount of
10%, 20% or 50% from the offering price of the shares if they agree not to transfer or pledge these shares for two, three or four years, respectively.

As of the date of this annual report, 762,886,886 of our common shares, representing 7.9% of our outstanding common shares were sold under the two programs mentioned above.

The current corporate income tax
rate in the Republic of China is 25%. We benefit from tax incentives generally available to technology companies in the Republic of China, including tax credits of up to 30% of the amount of some of our research and development, automation and
employee training expenditures. Starting in 2001, we also qualified for tax benefits at the rate of 5% to 20% of the amount of our investment in qualified equipment and technology. As a result, our effective tax rate was 18.1%, 27.7% and 26.6% in
2004, 2005 and 2006, respectively.

In 1997, the Income Tax Law of the Republic of China was amended to integrate corporate income tax and
shareholder dividend tax to eliminate the double taxation effect for resident shareholders of Taiwan companies. Under the amendment, all retained earnings generated from January 1, 1998 and not distributed to shareholders as dividends in the
following year are assessed with a 10% retained earnings tax. See Item 10. Additional InformationE. TaxationRepublic of China TaxationDividends. Historically, this has not had an impact on our financial results of
operations, because the majority of our earnings was distributed to the government by way of dividends. If we decide to distribute our earnings in the future, we may need to reserve the retained earnings tax recorded in the period during which the
related income is generated.

Our local telephone services had operating losses of NT$7.2 billion, NT$14.2 billion and NT$13.7 billion (US$0.4 billion) in 2004, 2005 and 2006, respectively. See Note 25 to our audited consolidated financial
statements included elsewhere in this annual report. We expect our local telephone services to continue incurring operating losses as competition in the local telephone services market further intensifies and traffic continues to migrate from fixed
line services to cellular and broadband services.

Our consolidated financial statements are prepared in accordance with US GAAP. The preparation of these consolidated financial statements requires us to
make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses as well as the disclosure of contingent assets and liabilities. We continually evaluate these estimates and judgments, including those
related to revenue recognition, allowance for doubtful accounts, estimated useful lives of long-lived assets, investments in unconsolidated companies, pension benefits and accounting for income taxes. We base these estimates and judgments on our
historical experience and other factors that we believe to be reasonable under the circumstances. Actual results may differ from these estimates.

We recognize revenues for our services in accordance with the Securities and Exchange Commission Staff Accounting Bulletin No. 104. We record service revenues over the periods they are earned. The costs of
providing services are recognized as incurred. Handset incentives are paid to third party dealers when they sell handsets to customers that enter into service contracts, and these are recognized as a cost of service when incurred. Usage revenues
from fixed line services, cellular services, internet and data services, and interconnection and call transfer fees from other telecommunications companies and carriers are billed in arrears and are recognized based upon minutes of traffic processed
when the services are provided in accordance with contract terms.

One-time subscriber connection fees, primarily in relation to fixed line
service revenues, are deferred and recognized over the average expected customer service periods, which we evaluate on a continual basis. For example, the average expected customer service period for fixed line service revenues has increased over
time from 13 years at December 31, 2004 to 16 years at December 31, 2006, and the average expected customer service period for cellular service revenues has declined over time from five years at December 31, 2004 to four years at
December 31, 2006 and the average expected customer service period for internet service revenues increased from three years in 2004 to four years in 2006, while the average expected customer service periods for other service lines have remained
relatively the same over the same period. If our estimates of these customer service periods become longer, the amortization of our deferred income could be materially and adversely affected.

When we enter into transactions which involve the provision of airtime bundled with products such as 3G data cards or handsets, the bundled arrangement
is accounted for in accordance with the Emerging Issues Task Force, or EITF, Issue No. 00-21, Revenue Arrangements with Multiple Deliverables. Total consideration received from handsets in these arrangements is allocated and measured using units of
accounting within the arrangement based on relative fair values limited to the amount that is not contingent upon the delivery of other items or services. Total consideration received from 3G data cards does not have objective and reliable fair
values for delivered and undelivered items; therefore, the recognition of revenues follows one unit of accounting.

When we sell products
to third party cellular phone stores, we record the direct sale of the products, typically handsets, as gross revenue when we are the primary obligor in the arrangement and when title is passed and the products are accepted by the stores. When we
also pay the third party cellular phone stores incentives to attract new customers and such incentives are identifiable, these incentives are accounted for as a reduction of revenue in accordance with EITF, Issue No. 01-09, Accounting for
Consideration Given by a Vendor to a Customer or a Reseller of the Vendors Products.

We maintain allowance for doubtful accounts for estimated losses that result from the inability of our customers to make required payments. We base our
allowances on the likelihood of recoverability of accounts receivable by operating segment based on past experience and current collection trends that we expect to continue. Our evaluation also includes the length of time the receivables are past
due, geographic concentrations and the general business environment. If changes in these factors occur, or the historical data we use to calculate the allowance provided for doubtful accounts does not reflect the future ability to collect
outstanding receivables, additional provisions for doubtful accounts may be needed and our future results of operations could be materially and adversely affected. Even as revenues have increased in recent years, the allowance for doubtful accounts
has decreased due to stricter credit investigations for new subscribers and more efficient collection activities for outstanding accounts.

A significant portion of our total assets consists of long-lived assets, primarily property,
plant and equipment and definite-lived intangibles. We estimate the useful lives of property, plant and equipment and other

long-lived assets with finite lives in order to determine the amount of depreciation and amortization expense to be recorded during the reported period. The
useful lives are estimated at the time assets are acquired and are based on historical experience with similar assets as well as the anticipated technological evolution or other environmental changes. If technological changes were to occur more
rapidly than anticipated or in a different form than anticipated, the useful lives assigned to these assets may need to be shortened, resulting in the recognition of increased depreciation and amortization in the relevant periods. Alternatively,
technological obsolescence could result in a write-down in the value of the assets to reflect impairment. We review these types of assets for impairment annually, or when events or circumstances indicate that the carrying amount may not be
recoverable over the remaining life of an asset. In assessing impairments, we use estimated cash flows that take into account managements estimates of future operations. We performed an impairment analysis and concluded that the paging
division assets were impaired and recognized an impairment loss of NT$343 million in 2005.

If at January 1, 2006 we would have
determined that the remaining useful lives for our property, plant and equipment were shorter or longer by one year than what we used in the preparation of our consolidated financial statements, our recorded depreciation expense in 2006 would have
increased by approximately NT$12.9 billion or decreased by approximately NT$8.1 billion, respectively.

We hold investments in other companies that we account for under the equity method or cost method of accounting, depending on our
ability to exert significant influence over the investee company. The amounts for our equity method investments generally represent our cost of the initial investment adjusted for our share of the investee companys income or loss and any
dividends received. The amounts for our cost method investments where the securities are not publicly traded generally represent our cost of the initial investment less any adjustments we make when we determine that an investments net
realizable value is less than its carrying cost.

The process of assessing whether a particular cost method investments net
realizable value is less than its carrying cost requires a significant amount of judgment. We periodically evaluate these long-term investments based on quoted market prices, if available, the financial condition of the investee company, economic
conditions in the industry and our intent and ability to hold the investment for a long period of time. If quoted market prices are not available, we estimate the fair value using the net asset values as well as the financial condition of the
investee company. This information may be based on information that we request from the investee companies and may not be subject to the same disclosure and audit requirements as required of U.S. companies, and as such, the reliability and accuracy
of the information may vary. If we deem the fair value of an investment to be less than the book value based on the above factors, and the decline in value is deemed to be other than temporary, we record the difference as impairment in the period of
occurrence. In 2005, we recognized a loss of NT$740 million, accounted for using the cost method, in relation to our investment in Taipei Financial Center Corporation due to lower than expected leasing rates for office and retail space in Taipei
101.

Estimating the net realizable value of investments in privately held companies can be inherently subjective and may contribute to
significant volatility in our reported results of operations. For example, if the investment environment worsens in 2007, we may incur an impairment in our equity or cost method investments.

The amounts recognized in
our consolidated financial statements related to pension benefits are determined on an actuarial basis that utilizes several different assumptions in the calculation of such amounts. Significant assumptions used in determining our pension benefits
are the discount rate, the expected long-term rate of return on plan assets, the rate of increase in compensation levels, and the average remaining years of service for employees, which prior to 2005 included an estimate for the number of employees
that will retire upon our privatization. In addition, because we were required to fully fund our pension plans on or prior to the date of our privatization to enable us to meet the requirements of making full benefit payments to our then existing
employees, prior to 2005 we made an assumption of our privatization date in determining the amount of the pension benefits.

We use long-term historical actual return information and estimate future long-term investment returns by
reference to external sources to develop the expected long-term return on plan assets. The discount rate is assumed based on the rates available on high-quality fixed-income debt instruments with the same period to maturity as the estimated period
to maturity of the pension benefit. We assume the rate of increase in compensation levels and average remaining years of service based on historical data. Any changes in one or more of these assumptions could impact our pension benefits.

A decrease in the discount rate or in the expected return on assets would increase the reported obligation. For example, if the discount rate in 2006
used in determining this obligation were 0.25% lower, it would generate a NT$125.4 million increase in the obligation reported on the balance sheet and a NT$66.7 million increase in the benefit costs. Similarly, if the expected return on assets
assumption were 0.25% lower, it would generate a NT$7.6 million increase in 2007 benefit costs. A minor change in the estimate of health care cost assumptions would not materially affect our pension obligations or related benefit costs. The MOTC
settled related pension obligations on the privatization date and recorded the difference between accrued pension liabilities, deferred pension cost and related deferred income tax assets as contributed capital in stockholders equity by
applying the guidance in AICPA Interpretation 39 to APB 16 Business combinations and FASB Implementation Guide, SFAS 88 Q&A 40.

As of December 31, 2006, we adopted SFAS No. 158, Employers Accounting for Defined Benefit Pensions and Other Postretirement Benefits. In accordance with this standard, we recorded the funded status of our
defined benefit pension as an asset or liability on our consolidated balance sheet with a corresponding offset, net of taxes, recorded in accumulated other comprehensive income (loss) within stockholders equity, resulting in an after-tax
decrease in equity of NT$226 million. Any changes in the pension obligation will have an equivalent impact on the funded status. The accumulated other income (loss) will also be impacted by the tax-adjusted amount.

Deferred income
taxes represent the effect of temporary differences between the amounts of assets and liabilities recognized for financial reporting purposes and the amounts recognized for income tax purposes. We measure deferred tax assets and liabilities using
statutory tax rates that, if changed, would result in either an increase or a decrease in the provision for income taxes in the period of change. A one-percentage point increase in the statutory income tax rate as of December 31, 2006 would
have decreased our net income by approximately NT$573.4 million.

We record a valuation allowance to reduce our deferred tax assets to the
amount of future tax benefit that is more likely than not to be realized. While we have considered future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for the valuation allowance, we cannot assure you
that we would not need to increase the valuation allowance to cover additional deferred tax assets that may not be realizable. Any increase in the valuation allowance could have a material adverse effect on our income tax provision and net income in
the period in which such determination is made.

We had a valuation allowance of NT$110 million on our deferred tax asset balance as of
December 31, 2006. We do not have a full valuation allowance on the deferred tax asset, as we believe these benefits will be fully realizable based on our projection of future operating income. If we experience a significant decrease in our
future operating income, the realizability of our deferred tax assets could be negatively impacted, and thus an increase in the valuation allowance might be required.

Our audited consolidated financial statements included in this
annual report are prepared under US GAAP. We intend to transition into financial reporting under ROC GAAP, with reconciliation to US GAAP, beginning in 2008. In the interim, we expect to continue to make available our quarterly and annual
consolidated financial statements prepared in accordance with US GAAP.

The following table sets forth our revenues, operating costs and expenses, income from operations and other financial data for the periods indicated.

Year ended December 31, 2005 compared with year ended December 31, 2006 Confirm all material trends have been highlighted in the year on year comparisons.

Our revenues increased by 0.9% from NT$184.7 million in 2005 to NT$186.3 billion
(US$5.7 billion) in 2006. This increase was primarily due to an increase in operating revenues of internet and data services.

Fixed line revenues comprised 35.9% and 33.8% of our revenues in 2005 and 2006, respectively. Our fixed line revenues decreased by 5.0%
from NT$66.3 billion in 2005 to NT$62.9 billion (US$1.9 billion) in 2006.

Local telephone services. Our local telephone revenues decreased by 4.3% from NT$40.7 billion in
2005 to NT$39.0 billion (US$1.2 billion) in 2006. This decrease was principally a result of a 12.0% decline in traffic volume from 21.1 billion minutes in 2005 to 18.6 billion minutes in 2006. This decline in traffic volume was primarily due to the
continued migration of non-HiNet internet subscribers from dial-up to broadband internet access, the continued traffic migration from fixed line services to broadband and cellular services, and increasing market competition. We expect this trend to
continue as broadband and cellular services become more widely adopted in Taiwan. However, we believe the rate of traffic migration from fixed-line services to broadband and cellular services is slowing. This decline in traffic volume was partially
offset by a 2.9% increase in average local usage fees, reflecting a continued decrease in the number of users of our discounted internet tariff package. Our local interconnection revenues decreased by NT$0.1 billion between these two years because
of a decrease in local interconnection volume.

Domestic long distance telephone services. Our domestic long distance telephone
revenues decreased by 9.7% from NT$11.0 billion in 2005 to NT$9.9 billion (US$303 million) in 2006. This decrease was mainly due to a decrease in traffic volume from 5.1 billion minutes in 2005 to 4.6 billion minutes in 2006. The decrease in traffic
volume was primarily due to the continued traffic migration from fixed line services to cellular services and increased competition from other fixed line operators and VoIP. The rate of migration from fixed line services to cellular services has
been slowing in the past two years as the cellular market becomes increasingly saturated. Our interconnection revenues also decreased as a result of more direct connections between private operators.

International long distance telephone services. Our international long distance telephone revenues decreased by 3.7% from NT$14.6 billion in 2005
to NT$14.0 billion (US$431 million) in 2006. This decrease was mainly due to intense market competition and a decrease in the average per minute usage charge due to promotional packages to encourage usage. This was partially offset by an 11.7%
increase in outgoing traffic volume from 2005 to 2006. Our international settlement revenues decreased by 8.1% from NT$3.3 billion in 2005 to NT$3.1 billion (US$94 million) in 2006. This decrease was primarily due to the continued decline in
international settlement rates.

Cellular revenues comprised 39.5% and 39.2% of our revenues in 2005 and 2006, respectively. Our cellular revenues remained flat at NT$73.0 billion (US$2.3 billion) in 2005 and in 2006. While we experienced an increase
in volume in 2006 from 2005, this was largely offset by tariff reductions which came into effect in June 2005 for SMS and in December 2005 for calls from mobile to fixed-line numbers. Outgoing traffic volume increased 3.4% from 8.9 billion minutes
in 2005 to 9.2 billion minutes in 2006, as a result of an increase in the number of customers using cellular service.

Internet and data revenues comprised 22.8% and 24.9% of our revenues in 2005 and 2006, respectively. Our internet and data revenues
increased by 9.9% from NT$42.2 billion in 2005 to NT$46.3 billion (US$1.4 billion) in 2006 due primarily to an increase in our internet services.

Internet services. Our revenues attributable to internet services increased by 11.0% from NT$32.1 billion in 2005 to NT$35.5 billion (US$1.1 billion) in 2006. This increase was largely due to an increase in the number of our ADSL
subscribers from 3.7 million as of December 31, 2005 to 3.9 million as of December 31, 2006. This increase was also due to a 4.7% increase in the number of our HiNet subscribers from 4.1 million as of December 31, 2005
to 4.3 million as of December 31, 2006. There was an increase in the number of FTTB customers from 20,000 in 2005 to 185,000 in 2006. However, the number of dial-up customers decreased from 1,166,092 in 2005 to 1,042,797 in 2006. Calls to
HiNet are recorded as part of our internet and data services and are not included in our local minutes or revenues. We include usage fees from fixed line telephone calls to access our HiNet service in our internet and data revenues. Usage fees from
fixed line telephone calls to access internet service providers other than HiNet are recorded as fixed line revenues.

Data services. Revenues from our data services increased by 6.6% from NT$10.1 billion in 2005 to
NT$10.8 billion (US$0.3 billion) in 2006. This increase was principally due to an increase in revenues from leased line services and additional operating revenue from our new subsidiary, Chief Telecom, in which we acquired a 70% interest in
September 2006. We continue to derive a substantial portion of our data revenues from leased line services. While demand for higher speed lease lines continues to increase, our overall leased line tariffs have continued to be adversely affected by
competition from other fixed line operators and international leased line service providers, as well as the continued migration of domestic leased line users to ADSL services.

Other revenues comprised 1.8% and 2.1% of our revenues in 2005 and 2006, respectively.

Our other revenues increased by 24.1% from NT$3.2 billion in 2005 to NT$4.1 billion (US$124 million) in 2006. This increase in other
revenues was primarily due to an NT$0.9 billion increase in revenues from our corporate solution business, MOD, real estate leasing and sales of 3G cellular handsets and data cards. This increase was partially offset by a NT$66 million decrease from
paging services, which beginning in 2006 is accounted for under Other.

Our operating costs and expenses decreased by 6.8% from NT$139.6 billion in 2005 to NT$130.0 billion (US$4.0 billion) in 2006. This decrease was primarily
due to decreases in stock compensation expenses. As a percentage of revenues, operating costs and expenses decreased from 75.5% in 2005 to 69.8% in 2006.

Our costs of
revenues decreased by 8.0% from NT$68.1 billion in 2005 to NT$62.6 billion (US$1.9 billion) in 2006. This decrease was principally a result of: an NT$7.2 billion decrease in employees purchases of our common shares at discounts under our
priority share subscription program; a NT$438 million profit increase resulting from sales of fixed assets; NT$383 million increase in contractual penalty payments from third-party contractors relating to project delays and a NTS369 million income
increase due to sales of scrap inventory. This decrease was partially offset by an NT$1.2 billion increase in our handset incentives and an NT$1.2 billion increase in special termination benefits under our early retirement program. We recognize
compensation expense when our employees purchase our common shares at discounts under the priority share subscription program.

Our marketing expenses, which include personnel expenses, provisions for bad debt and expenses relating to advertising and other
marketing-related activities, decreased by 12.7% from NT$23.7 billion in 2005 to NT$20.6 billion (US$0.6 billion) in 2006. This decrease was mainly due to an NT$4.0 billion decrease in employees purchases of our common shares at discounts
under our priority share subscription program, and partially offset by an NT$0.8 billion increase in special termination benefits under our early retirement program.

Our general and administrative expenses decreased by 5.4% from NT$3.5
billion in 2005 to NT$3.3 billion (US$0.1 billion) in 2006. This decrease was primarily due to a decrease of NT$0.7 billion in compensation expense due to a decrease in employees purchases of our common shares at discounts under our
employee priority share subscription program. This decrease was partially offset by an increase of NT$0.2 billion in special termination benefits under our early retirement program and an NT$0.2 billion increase in donations to non-profit
organizations.

Our research and development expenses decreased by 10.2% from NT$3.1 billion in 2005 to NT$2.8 billion (US$87 million) in 2006. This decrease was primarily due to a decrease of NT$0.5 billion in compensation expense
due to a decrease in employees purchase of our common shares at discounts under our employee priority share subscription program, and partially offset by an increase of NT$53 million in special termination benefit under early retirement
program. Our research and development expenses decreased as a percentage of our revenues from 1.7% in 2005 to 1.5% in 2006.

Our depreciation and amortization expenses decreased by 1.2% from NT$41.2 billion in 2005 to NT$40.7 billion (US$1.2
billion) in 2006. This decrease was mainly due to decreases in capital expenditure since 2002, and partially offset by the amortization of our 3G license.

Beginning with the fiscal year ended December 31, 2006, we no longer combine cellular and paging services in one business segment. Instead, operating costs and expenses from
paging services are included in Other. For this reason, operating costs and expenses for 2005 have been reclassified on a comparable basis.

Our local telephone operating expenses, excluding depreciation and amortization, decreased by 3.5%
from NT$36.0 billion in 2005 to NT$34.7 billion (US$1.1 billion) in 2006, primarily due to an NT$4.4 billion decrease in employees purchases of our common shares at discount under our employee priority share subscription program, partially
offset by an NT$1.6 billion increase in special termination benefits under our early retirement program, an NT$1.1 billion increase in bonus for employees and remuneration for directors and supervisors and an NT$0.6 billion increase in
performance-based bonuses. Our depreciation and amortization expenses relating to local telephone services decreased by 5.6% from NT$19.0 billion in 2005 to NT$18.0 billion (US$0.6 billion) in 2006. The decrease was primarily due to a decrease in
depreciation expenses because of an increase in obsolete equipment.

Our domestic long distance telephone operating expenses, excluding depreciation and amortization, decreased by 17.8% from NT$1.5 billion in 2005 to NT$1.2
billion (US$38 million) in 2006,primarily due to an NT$0.2 billion decrease in the employees purchases of our common shares at discount under our employee priority share subscription program. Our depreciation and amortization expenses relating
to domestic long distance telephone services remained flat at NT$0.7 billion in 2005 and in 2006.

Our international long distance telephone operating expenses, excluding depreciation and amortization, decreased by 8.4% from NT$7.6
billion in 2005 to NT$7.0 billion (US$0.2 billion) in 2006. The decrease was primarily due to an NT$0.4 billion decrease in the employees purchase of our common shares at discounts and an NT$0.8 billion decrease in international long distance
telephone settlement fees; partially offset by an NT$0.2 billion increase in material expenses and an NT$0.2 billion increase in interconnection fees. Our depreciation and amortization expenses relating to international long distance telephone
services decreased by 16.8% from NT$0.7 billion in 2005 to NT$0.5 billion (US$17 million) in 2006. The decrease in depreciation and amortization expenses was mainly due to a decrease in expenditures relating to equipment upgrades.

Our cellular operating expenses,
excluding depreciation and amortization, increased by 1.5% from NT$22.8 billion in 2005 to NT$23.1 billion (US$0.7 billion) in 2006. This increase was primarily due to an NT$1.1 billion increase in marketing expenses, an NT$0.2 billion increase in
bonus for employees and remuneration for directors and supervisors and a NT$0.2 billion increase in special termination benefits under our early retirement program partially offset by an NT$1.2 billion decrease in the employees purchases of
our common shares at discounts under our employee priority share subscription program. Our depreciation and amortization expenses relating to cellular services increased by 10.9% from NT$7.4 billion in 2005 to NT$8.2 billion (US$0.3 billion) in
2006. The increase was mainly due to an NT$0.5 billion increase in depreciation caused by purchases of new equipment such as mobile exchangers and signal transmitters and receivers; and an NT$0.3 billion increase in amortization of 3G license fees.

Our
internet and data operating expenses, excluding depreciation and amortization, decreased by 29.2% from NT$22.4 billion in 2005 to NT$15.8 billion (US$0.5 billion) in 2006. This decrease was primarily due to an NT$5.3 billion decrease in the
employees purchases of our common shares at discounts under our employee priority share subscription program; and an NT$1.1 billion decrease in printing and mailing expenses of bills after the business was relocated to local telephone
services. Our depreciation and amortization expenses relating to internet and data services remained flat at NT$12.4 billion in 2005 and in 2006.

As a result of the foregoing, our operating income increased by 24.7% from NT$45.1 billion in 2005 to NT$56.3 billion (US$1.7 billion) in 2006. Our
operating margin increased from 24.5% in 2005 to 30.2% in 2006.

Beginning with the fiscal year ended December 31, 2006, we no longer combine cellular and paging services in one business segment. Instead, income from operations from paging
services are included in Other. For this reason, income from operations for 2005 have been reclassified on a comparable basis.

As a result of the foregoing, in 2005 compared to 2006 operating loss for our local telephone services decreased by 4% from NT$14.2 billion to NT$13.6 billion (US$0.4 billion); operating income for our domestic long distance telephone
services decreased by 8.4% from NT$8.7 billion to NT$8.0 billion (US$0.2 billion); operating income for our international long distance telephone services increased by 3.4% from NT$6.3 billion to NT$6.5 billion (US$0.2 billion); operating income for
our cellular services decreased by 2.7% from NT$42.8 billion to NT$41.7 billion (US$1.3 billion); and operating income for our internet and data services increased by 145% from NT$7.4 billion to NT$18.1 billion (US$0.6 billion).

Our management evaluates our business segments taking into account internal and inter-segment costs and revenues. All of our business lines, particularly
local telephone, domestic long distance telephone and international long distance telephone services, operate as an integrated business unit. Therefore, we have shown the inter-segment income in the above table.

Our other
income decreased by 22.2% from NT$2.0 billion in 2005 to NT$1.6 billion (US$47 million) in 2006. This decrease was primarily due to an NT$0.2 billion decrease in rental income as rental income was recategorized from other income in 2005 to
revenueother in 2006 and an NT$0.1 billion decrease in foreign exchange loss. We recategorized rental income from other income to revenuesother in 2006 as we have begun investing in real estate revitalization projects as part of our
efforts to make more productive use of certain undeveloped or underdeveloped properties that we own and therefore expect rental income will increase in future years.

Our other expenses decreased by 55.2% from NT$1.1 billion in 2005 to NT$0.5 billion (US$15 million) in 2006. This decrease was largely due to a NT$740 million impairment loss on our long-term investment in the Taipei
101 building in 2005.

Our revenues decreased by 0.3% from NT$185.2 million in 2004 to NT$184.7 billion (US$5.6 billion) in 2005. This decrease was primarily due to a continuous
decline in fixed network business and an expansion of the average expected customer service period which affects the revenue from fixed network.

Fixed line revenues comprised 38.9% and 35.9% of our revenues in 2004 and 2005, respectively. Our fixed line revenues
decreased by 8.0% from NT$72.1 billion in 2004 to NT$66.3 billion (US$2.0 billion) in 2005.

Local telephone services. Our local
telephone revenues decreased by 9.3% from NT$44.9 billion in 2004 to NT$40.7 billion (US$1.2 billion) in 2005. This decrease was principally a result of a 14.0% decline in traffic volume from 24.5 billion minutes in 2004 to 21.1 billion minutes in
2005. This decline in traffic volume was primarily due to the continued migration of non-HiNet internet subscribers from dial-up to broadband internet access, the continued traffic migration from fixed line services to broadband and cellular
services, and increasing market competition. We expect this trend to continue as broadband and cellular services become more widely adopted in Taiwan. However, we believe the rate of traffic migration from fixed-line services to broadband and
cellular services is slowing. This decline in traffic volume was partially offset by a 2.9% increase in average local usage fees, reflecting a continued decrease in the number of users of our discounted internet tariff package. The decrease was also
due to the expansion of the customer service period from an average of 13 years to 16 years, which has caused a substantial decline in revenues in local telephone connection fees. Our local interconnection revenues decreased by NT$0.1 billion
between these two years because of a decrease in local interconnection volume.

Domestic long distance telephone services. Our
domestic long distance telephone revenues decreased by 8.3% from NT$12.0 billion in 2004 to NT$11.0 billion (US$0.3 billion) in 2005. This decrease was mainly due to a decrease in traffic volume from 5.6 billion minutes in 2004 to 5.1 billion
minutes in 2005. The decrease in traffic volume was primarily due to the continued traffic migration from fixed line services to broadband and cellular services and increased competition from other fixed line operators. The rate of migration from
fixed line services to cellular services has been slowing in the past two years as the cellular market becomes increasingly saturated. Our interconnection revenues also decreased as a result of more direct connections between private operators.

International long distance telephone services. Our international long distance telephone revenues decreased by 4.1% from NT$15.2
billion in 2004 to NT$14.6 billion (US$0.4 billion) in 2005. This decrease was mainly due to intense market competition and a decrease in the average per minute usage charge due to promotional packages to encourage usage. This was partially offset
by an 8% increase in outgoing traffic volume from 2004 to 2005. Our international settlement revenues decreased by 5.6% from NT$3.5 billion in 2004 to NT$3.3 billion (US$0.1 billion) in 2005. This decrease was primarily due to the continued decline
in international settlement rates and translation losses due to fluctuations in foreign exchange rates.

Our cellular services grew as a percentage of our revenues from 38.0% in 2004 to 39.5% in 2005. Our cellular services revenues increased by 3.9% from NT$70.3 billion in 2004 to NT$73.0 billion (US$2.2 billion) in
2005. This increase was mainly a result of an increase in outgoing traffic volume of 2.9% from 8.7 billion minutes in 2004 to 8.9 billion minutes in 2005, as a result of an increase in the number of customers using monthly rental service.

Internet
and data revenues comprised 21.2% and 22.8% of our revenues in 2004 and 2005, respectively. Our internet and data revenues increased by 7.2% from NT$39.3 billion in 2004 to NT$42.2 billion (US$1.3 billion) in 2005 due primarily to an increase in our
internet services.

Internet services. Our revenues attributable to internet services increased by 8.6% from NT$29.5 billion in 2004
to NT$32.1 billion (US$1.0 billion) in 2005. This increase was largely due to an increase in the number of our ADSL subscribers from 3.1 million as of December 31, 2004 to 3.7 million as of December 31, 2005. This increase was
also due to a 7.6% increase in the number of our HiNet subscribers from 3.8 million as of December 31, 2004 to 4.1 million as of December 31, 2005. Calls to HiNet are recorded as part of our internet and data services and are not
included in our local minutes or revenues. We include usage fees from fixed line telephone calls to access our HiNet service in our internet and data revenues. Usage fees from fixed line telephone calls to access internet service providers other
than HiNet are recorded as fixed line revenues.

Data services. Revenues from our data services increased by 3.0% from NT$9.8
billion in 2004 to NT$10.1 billion (US$0.3 billion) in 2005. This increase was principally due to an increase in revenues from our hiLink virtual private network service. We continue to derive a substantial portion of our data revenues from leased
line services. While demand for higher speed lease lines continues to increase, our overall leased line tariffs have continued to be adversely affected by competition from other fixed line operators and international leased line service providers,
as well as the continued migration of domestic leased line users to ADSL services. The effects of tariff decreases were generally offset by the continued increase in the usage of our leased line services in 2005.

Other revenues comprised 1.9% and 1.8% of our
revenues in 2004 and 2005, respectively.

Our other revenues decreased by 6.7% from NT$3.5 billion in 2004 to NT$3.2 billion (US$99.7
million) in 2005. This decrease in other revenues was primarily due to an NT$0.3 billion decrease in revenues from our corporate solution business and a decrease in revenues of NT$0.2 billion from our paging services.

Our operating
costs and expenses increased by 12.8% from NT$123.7 billion in 2004 to NT$139.6 billion (US$4.3 billion) in 2005. This increase was primarily due to increases in stock compensation expenses and performance-based bonuses. As a percentage of revenues,
operating costs and expenses increased from 66.8% in 2004 to 75.5% in 2005.

Our costs of revenues increased by 16.0% from NT$58.7 billion in 2004 to
NT$68.1 billion (US$2.1 billion) in 2005. This increase was principally a result of: an NT$7.2 billion increase in employees purchase of our

Our marketing expenses, which include personnel expenses, provisions for bad debt and
expenses relating to advertising and other marketing-related activities, increased by 22.6% from to NT$19.3 billion in 2004 to NT$23.7 billion (US$0.7 billion) in 2005. This increase was mainly due to an NT$4.0 billion increase in employees
purchase of our common shares at discounts and an NT$0.4 billion increase in performance-based bonuses. We recognize compensation expense when our employees purchase our common shares at discounts under the priority share subscription program.

Our
general and administrative expenses increased by 37.5% from NT$2.5 billion in 2004 to NT$3.5 billion (US$0.1 billion) in 2005. This increase was primarily due to an increase of NT$0.7 billion in compensation expense arising under our employee
priority share subscription program; and an increase of NT$76 million in performance-based bonuses. We recognize compensation expense when our employees purchase our common shares at discounts under the priority share subscription program. The
higher compensation expense in 2005 was largely due to an increase in such purchases by our employees compared to 2004.

Our research and development expenses increased by 27.0% from NT$2.5 billion in 2004 to NT$3.1 billion (US$0.1 billion) in 2005. This
increase was primarily due to an increase of NT$0.5 billion in compensation expense as a result of an increase in employees purchases of our common shares at a discount under our employee priority share subscription program and an increase of
NT$74 million in performance-based bonuses. Our research and development expenses increased as a percentage of our revenues from 1.3% in 2004 to 1.7% in 2005.

Our depreciation and amortization expenses increased by 1.1% from NT$40.7 billion in 2004 to
NT$41.2 billion (US$1.3 billion) in 2005. This increase was mainly due to the amortization of our 3G licence.

Beginning with the fiscal year ended December 31, 2006, we no longer combine cellular and paging services in one business segment. Instead, operating costs and expenses from
paging services are included in Other. For this reason, operating costs and expenses for 2004 and 2005 have been reclassified on a comparable basis.

Our local telephone operating expenses, excluding depreciation and amortization, increased by
11.8% from NT$32.2 billion in 2004 to NT$36.0 billion (US$1.1 billion) in 2005. This increase was primarily due to an NT$4.5 billion increase in employees purchase of our common shares at discount. Our depreciation and amortization expenses
relating to local telephone services decreased by 4.9% from NT$20.0 billion in 2004 to NT$19.0 billion (US$0.6 billion) in 2005. The decrease was a result of a decrease in depreciation and amortization expenses because of an increase in obsolete
equipment.

Our domestic long distance telephone operating expenses, excluding depreciation and amortization, increased by 23.2% from NT$1.2 billion in 2004 to NT$1.5 billion (US$46 million) in 2005. The increase was primarily
due to an NT$0.2 billion increase in the employees purchase of our common shares at discount. Our depreciation and amortization expenses relating to domestic long distance telephone services decreased by 12.7% from NT$0.8 billion in 2004 to
NT$0.7 billion (US$21.9 million) in 2005. The decrease in depreciation and amortization expenses was mainly due to a slow-down of our upgrading equipment.

Our international long distance telephone operating expenses, excluding
depreciation and amortization, increased by 1.0% from NT$7.5 billion in 2004 to NT$7.6 billion (US$0.2 billion) in 2005. The increase was primarily due to an NT$0.35 billion increase in the employees purchase of our common shares at discounts.
Our depreciation and amortization expenses relating to international long distance telephone services remained flat at NT$0.7 billion in 2004 and in 2005.

Our cellular operating expenses, excluding depreciation and amortization, increased by 14.3% from NT$19.9 billion in 2004 to NT$22.8 billion (US$0.7 billion) in 2005. This increase was primarily due to an NT$1.2
billion increase in the employees purchase of our common shares at discounts and an NT$1 billion increase in marketing expenses. Our depreciation and amortization expenses relating to cellular services increased by 25.8% from NT$5.9 billion in
2004 to NT$7.4 billion (US$0.2 billion) in 2005. The increase was mainly due to an NT$1.0 billion increase in depreciation caused by purchases of new equipment such as mobile exchangers and signal transmitters and receivers and an NT$0.4 billion
increase in amortization of 3G license fees.

Our internet and data operating expenses, excluding depreciation and amortization, increased by 37.8% from NT$16.2 billion in 2004 to NT$22.4 billion
(US$0.7 billion) in 2005. This increase was primarily due to an NT$5.3 billion increase in the employees purchase of our common shares at discounts. Our depreciation and amortization expenses relating to internet and data services remained
flat at NT$12.4 billion in 2004 and in 2005.

Operating Income and Operating Margin

As a result of the foregoing, our operating income decreased by 26.5% from NT$61.5 billion in 2004 to NT$45.1 billion (US$1.4 billion) in 2005. Our
operating margin decreased from 33.2% in 2004 to 24.5% in 2005.

Beginning with the fiscal year ended December 31, 2006, we no longer combine cellular and paging services in one business segment. Instead, income from operations from paging
services are included in Other. For this reason, income from operations for 2004 and 2005 have been reclassified on a comparable basis.

As a result of the foregoing, in 2004 compared to 2005 operating loss for our local telephone services increased by 96.6% from NT$7.2 billion to NT$14.2 billion (US$434.3 million); operating income for our domestic
long distance telephone services decreased by 11.8% from NT$9.9 billion to NT$8.7 billion (US$265.9 million);

operating income for our international long distance telephone services decreased by 9.9% from NT$7.0 billion to NT$6.3 billion (US$192.1 million); operating
income for our cellular services decreased by 3.7% from NT$44.5 billion to NT$42.8 billion (US$1.3 billion); and operating income for our internet and data services decreased by 31.1% from NT$10.7 billion to NT$7.4 billion (US$225.4 million).

Our management evaluates our business segments taking into account internal and inter-segment costs and revenues. All of our business
lines, particularly local telephone, domestic long distance telephone and international long distance telephone services, operate as an integrated business unit. Therefore, we have shown the inter-segment income in the above table.

Our other
income increased by 75.9% from NT$1.1 billion in 2004 to NT$2.0 billion (US$60 million) in 2005. This increase was primarily due to an NT$228 million increase in interest income, an NT$128 million increase in gains on sales of short-term investment
and an NT$90 million increase resulting from equity in earnings of unconsolidated companies.

Our other expenses increased by 163.8% from
NT$0.4 billion in 2004 to NT$1.1 billion (US$34 million) in 2005. This increase was largely due to a NT$740 million impairment loss on our long-term investment in the Taipei 101 building in 2005.

Our primary source of liquidity is cash flow from operations, which represents operating profit
adjusted for non-cash items, primarily depreciation and amortization and changes in current assets and liabilities. We believe that our working capital is sufficient for our present requirements.

In 2006, our net cash provided by operating activities totaled NT$100.1 billion (US$3.1 billion), compared with NT$86.2 billion in 2005. This increase
was primarily due to an NT$10.1 billion decrease in income tax

expenditure. In 2005, our net cash provided by operating activities totaled NT$86.2 billion compared with NT$91.6 billion in 2004. This decrease was
primarily due to a decrease in net income.

Historically, net cash provided by operating activities has been sufficient to cover our
capital expenditures, including the ongoing expansion and modernization of our networks. Our net cash used in investing activities decreased from NT$28.0 billion in 2005 to NT$19.1 billion (US$0.6 billion) in 2006, principally as a result of an
NT$12.7 billion increase in purchases and sales of short-term investments offset by NT$4.8 billion increase in acquisition of property, plant and equipment. Our net cash used in investing activities decreased from NT$32.4 billion in 2004 to NT$28.0
billion in 2005, principally as a result of an NT$4.3 billion decrease in purchases and sales of short-term investments.

In 2006, our net
cash used in financing activities totaled NT$52.2 billion (US$1.6 billion), which reflected NT$40.7 billion of payment of dividends and NT$11.4 billion of purchase of treasury stock during that period. In 2005, our net cash used in financing
activities totaled NT$45.6 billion, which reflected NT$45.3 billion of payment of dividends during that period. In 2004, our net cash used in financing activities totaled NT$43.4 billion, which reflected NT$43.4 billion of payment of dividends
during that period.

In future years, we
expect to have capital expenditure requirements for the ongoing expansion and upgrade of our networks combined with anticipated outlays for the introduction of new services, including our 3G cellular services. We also expect to make dividend
payments on an ongoing basis. See Item 8. Financial InformationA. Consolidated Statements and Other Financial Information. Furthermore, we may require working capital from time to time to finance purchases of materials for our
maintenance and other overhead expenses. We expect to primarily rely on cash generated from operations and, to a lesser extent, loans from commercial banks to meet our planned capital expenditures, make our planned dividend payments, repay debts and
fulfill other commitments over the next 12 months.

As of December 31, 2006, our primary source of liquidity was NT$70.7 billion
(US$2.2 billion) of cash and cash equivalents. We had a portfolio of interest-free debt of approximately NT$0.7 billion, NT$0.5 billion and NT$0.3 billion (US$9.2 million) as of December 31, 2004, 2005 and 2006, respectively. Our only long-term
loan has a five-year term with three annual installment payments due beginning in March 2005 and ending in March 2007. We are not subject to any covenants under any of our long-term loan facilities.

On November 18, 2005, our subsidiary Chief Telecom Inc. obtained a secured loan in the amount of NT$23 million from Chinatrust Commercial Bank at an
annual interest rate of 3.05%. Interest and principle are payable monthly and the secured loan is due by November 18, 2007. Chief Telecom Inc. also has short-term loans in the amount of NT$126 million at a floating rate equivalent to the
two-year time deposit interest rate plus 0.7%, which will be due on October 11, 2007.

In 1995, we and several other public utilities
companies in Taiwan were required by the Republic of China government to contribute funds as a part of the governments effort to upgrade the existing telecommunication and other infrastructure in Taiwan. As of December 31, 2006, we have
contributed NT$2.0 billion to the funds, and the contributions were accounted for as Other assets- Other on our balance sheets. If the contributions to the funds are not sufficient to finance the construction of the new underground fixed
lines and conduits, the contributors to the funds and the governmental agencies will determine if and when to raise additional capital and the amounts of such contributions from each party. This fund allows us to obtain unsecured interest-free loans
up to the original amount contributed to the fund. As of December 31, 2006, we had total outstanding borrowings of NT$0.3 billion from this fund, which is due within one year. We are not required to provide any collateral to secure these
borrowings.

We have a revolving credit facility with a term of one year. As of December 31, 2006, we had not
made any drawdowns under this facility. We are not subject to any covenants for borrowings under this facility. In the past, we had from time to time issued commercial paper to fund our working capital needs. In 2006, we did not issue any commercial
paper. We may issue commercial paper in the future for our short-term cash requirements.

We have not entered into any financial guarantees
or similar commitments to guarantee the payment obligations of third parties. In addition, we do not have any written options on non-financial assets.
